Bitcoin - The Currency of the Internet

A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.

Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever. While bitcoin tokens on the original network can't be copied or counterfeited, the protocol is open source and can be recreated with different parameters. We call these Airdrops.

Is there any insider trading regulation in Bitcoin? (example in comments)

Lets say that a major company, Amazon for example, decides to start accepting Bitcoins. My assumption (which may be wrong) would be that the price of Bitcoin would soar by increasing legitimacy and demand for the cryptocurrency. Would it be illegal for those in the know (ie Amazon execs) to hoard bitcoins in the weeks before the announcement and sell at a much higher price?

Eth 2.0 vs Polkadot and other musings by a fundamental investor

Spent about two hours on this post and I decided it would help the community if I made it more visible. Comment was made as a response to this
I’m trying to avoid falling into a maximalist mindset over time. This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech.
Can someone help me see the downsides of diversifying into DOTs?
I know Polkadot is more centralized, VC backed, and generally against our ethos here. On chain governance might introduce some unknown risks. What else am I missing?
I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
Response:
What else am I missing?
The upsides.
Most of the guys responding to you here are full Eth maxis who drank the Parity is bad koolaid. They are married to their investment and basically emotional / tribal in an area where you should have a cool head. Sure, you might get more upvotes on Reddit if you do and say what the crowd wants, but do you want upvotes and fleeting validation or do you want returns on your investment? Do you want to be these guys or do you want to be the shareholder making bank off of those guys?
Disclaimer: I'm both an Eth whale and a Dot whale, and have been in crypto for close to a decade now. I originally bought ether sub $10 after researching it for at least a thousand hours. Rode to $1500 and down to $60. Iron hands - my intent has always been to reconsider my Eth position after proof of stake is out. I invested in the 2017 Dot public sale with the plan of flipping profits back to Eth but keeping Dots looks like the right short and long term play now. I am not a trader, I just take a deep tech dive every couple of years and invest in fundamentals.
Now as for your concerns:
I know Polkadot is more centralized
The sad truth is that the market doesn't really care about this. At all. There is no real statistic to show at what point a coin is "decentralized" or "too centralized". For example, bitcoin has been completely taken over by Chinese mining farms for about five years now. Last I checked, they control above 85% of the hashing power, they just spread it among different mining pools to make it look decentralized. They have had the ability to fake or block transactions for all this time but it has never been in their best interest to do so: messing with bitcoin in that way would crash its price, therefore their bitcoin holdings, their mining equipment, and their company stock (some of them worth billions) would evaporate. So they won't do it due to economics, but not because they can't.
That is the major point I want to get across; originally Bitcoin couldn't be messed with because it was decentralized, but now Bitcoin is centralized but it's still not messed with due to economics. It is basically ChinaCoin at this point, but the market doesn't care, and it still enjoys over 50% of the total crypto market cap.
So how does this relate to Polkadot? Well fortunately most chains - Ethereum included - are working towards proof of stake. This is obviously better for the environment, but it also has a massive benefit for token holders. If a hostile party wanted to take over a proof of stake chain they'd have to buy up a massive share of the network. The moment they force through a malicious transaction a proof of stake blockchain has the option to fork them off. It would be messy for a few days, but by the end of the week the hostile party would have a large amount of now worthless tokens, and the proof of stake community would have moved on to a version of the blockchain where the hostile party's tokens have been slashed to zero. So not only does the market not care about centralization (Bitcoin example), but proof of stake makes token holders even safer.
That being said, Polkadot's "centralization" is not that far off to Ethereum. The Web3 foundation kept 30% of the Dots while the Ethereum Foundation kept 17%. There are whales in Polkadot but Ethereum has them too - 40% of all genesis Ether went to 100 wallets, and many suspect that the original Ethereum ICO was sybiled to make it look more popular and decentralized than it really was. But you don't really care about that do you? Neither do I. Whales are a fact of life.
VC backed
VCs are part of the crypto game now. There is no way to get rid of them, and there is no real reason why you should want to get rid of them. They put their capital at risk (same as you and me) and seek returns on their investment (same as you and me). They are both in Polkadot and Ethereum, and have been for years now. I have no issue with them as long as they don't play around with insider information, but that is another topic. To be honest, I would be worried if VCs did not endorse chains I'm researching, but maybe that's because my investing style isn't chasing hype and buying SUSHI style tokens from anonymous (at the time) developers. That's just playing hot potato. But hey, some people are good at that.
As to the amount of wallets that participated in the Polkadot ICO: a little known fact is that more individual wallets participated in Polkadot's ICO than Ethereum's, even though Polkadot never marketed their ICO rounds due to regulatory reasons.
generally against our ethos here
Kool aid.
Some guy that works(ed?) at Parity (who employs what, 200+ people?) correctly said that Ethereum is losing its tech lead and that offended the Ethereum hivemind. Oh no. So controversial. I'm so personally hurt by that.
Some guy that has been working for free on Ethereum basically forever correctly said that Polkadot is taking the blockchain tech crown. Do we A) Reflect on why he said that? or B) Rally the mob to chase him off?
"I did not quit social media, I quit Ethereum. I did not go dark, I just left the community. I am no longer coordinating hard forks, building testnets, or contributing otherwise. I did not work on Polkadot, I never did, I worked on Ethereum. I did not hate Ethereum, I loved it."
Also Parity locked their funds (and about 500+ other wallets not owned by them) and proposed a solution to recover them. When the community voted no they backed off and did not fork the chain, even if they had the influence to do so. For some reason this subreddit hates them for that, even if Parity did the 100% moral thing to do. Remember, 500+ other teams or people had their funds locked, so Parity was morally bound to try its best to recover them.
Its just lame drama to be honest. Nothing to do with ethos, everything to do with emotional tribalism.
Now for the missing upsides (I'll also respond to random fragments scattered in the thread):
This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech.
A good quick intro to Eth's tech vs Polkadot's tech can be found on this thread, especially this reply. That thread is basically mandatory reading if you care about your investment.
Eth 2.0's features will not really kick in for end users until about 2023. That means every dapp (except DeFI, where the fees make sense due to returns and is leading the fee market) who built on Eth's layer 1 are dead for three years. Remember the trading card games... Gods Unchained? How many players do you think are going to buy and sell cards when the transaction fee is worth more than the cards? All that development is now practically worthless until it can migrate to its own shard. This story repeats for hundreds of other dapp teams who's projects are now priced out for three years. So now they either have to migrate to a one of the many unpopulated L2 options (which have their own list of problems and risks, but that's another topic) or they look for another platform, preferably one interoperable with Ethereum. Hence Polkadot's massive growth in developer activity. If you check out https://polkaproject.com/ you'll see 205 projects listed at the time of this post. About a week ago they had 202 listed. That means about one team migrated from another tech stack to build on Polkadot every two days, and trust me, many more will come in when parachains are finally activated, and it will be a complete no brainer when Polkadot 2.0 is released.
Another huge upside for Polkadot is the Initial Parachain Offerings. Polkadot's version of ICOs. The biggest difference is that you can vote for parachains using your Dots to bind them to the relay chain, and you get some of the parachain's tokens in exchange. After a certain amount of time you get your Dots back. The tokenomics here are impressive: Dots are locked (reduced supply) instead of sold (sell pressure) and you still earn your staking rewards. There's no risk of scammers running away with your Ether and the governance mechanism allows for the community to defund incompetent devs who did not deliver what was promised.
Wouldn’t an ETH shard on Polkadot gain a bunch of scaling benefits that we won’t see natively for a couple years?
Yes. That is correct. Both Edgeware and Moonbeam are EVM compatible. And if the original dapp teams don't migrate their projects someone else will fork them, exactly like SUSHI did to Uniswap, and how Acala is doing to MakerDao.
Although realistically Ethereum has a 5 yr headstart and devs haven't slowed down at all
Ethereum had a five year head start but it turns out that Polkadot has a three year tech lead.
Just because it's "EVM Compatible" doesn't mean you can just plug Ethereum into Polkadot or vica versa, it just means they both understand Ethereum bytecode and you can potentially copy/paste contracts from Ethereum to Polkadot, but you'd still need to add a "bridge" between the 2 chains, so it adds additional complexity and extra steps compared to using any of the existing L2 scaling solutions
That only applies of you are thinking from an Eth maximalist perspective. But if you think from Polkadot's side, why would you need to use the bridge back to Ethereum at all? Everything will be seamless, cheaper, and quicker once the ecosystem starts to flourish.
I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
They are competitors. Both have their strategies, and both have their strengths (tech vs time on the market) but they are clearly competing in my eyes. Which is a good thing, Apple and Samsung competing in the cell phone market just leads to more innovation for consumers. You can still invest in both if you like.

Edit 2 - one day later PolkaProject count is 210. Devs are getting the hint :)

Earning Passive Income with Crypto Staking (Legit!)

Okay. So, whether you are new or have been with the bitcoin community for a while, you might not have heard of cryptocurrency staking. Madali lang sya, promise.
I will share my experience at the end of this post, pero ano nga ba ang Staking?

[SKIP THIS PORTION AND GO TO "HOW TO?" IF YOU DON'T WANT TO BE BORED WITH HISTORY]

Compared to bitcoin mining, na sobrang hirap na kasi kailangan mo ng magandang CPU/GPU para lang magka-pera ka. Hindi na sya profittable, kasi malakas sya sa kuryente at bibili ka pa ng mga hardware.
Mas eco-friendly ang Crypto Staking. Para syang investment, actually. Hahawak ka lang ng pera sa wallet mo. Mas malaki ang laman ng wallet mo, mas malaki din kita mo. Simple, right?
Bakit? Let me introduce you to altcoins. Ang altcoins ay mga cryptocurrency na hindi bitcoin. Example ng mga altcoins ay Ethereum, Litecoin, Dogecoin, and marami pa sila.
May mga altcoins na Proof-of-Work (POW). Meaning, kailangan mo talaga ng magandang hardware para maka-mine ka ng bagong coins. On the other hand, may mga Proof-of-Stake (POS) naman na altcoins. Sa mga POS na altcoins, hindi mo kailangan ng napakagandang gaming computer katulad ni Alodia. Ang need mo lang is magkalaman ang wallet mo, at gamit ang balance sa waller, is magva-validate ng mga bagong altcoins. Hindi na ako mag-eexplain pa dahil baka ma bored kayo, so check nyo nalang tong article na to para mas maintindihan nyo: https://www.investopedia.com/terms/p/proof-stake-pos.asp#:~:text=Proof%20of%20Stake%20(PoS)%20concept,power%20he%20or%20she%20has%20concept,power%20he%20or%20she%20has).
---------------------------------------------
How to?
So paano nga tayo kikita ng passive income dito? Para syang interest - gagamitin ang balance nyo para makagawa ng bagong altcoins. In exchange, may makukuha ka rin sa mga bagong na-validate. Para sayng interest sya bankgo, mas malaki hawak mo, mas malaki din kita mong interest.
I won't beat around the bush any longer. Here's how you can start:
Ref | Non-Ref
Use either of the link above to register to Coinstake.in. Bale, ibibgay nating ang "staking rights" sa kanila. Sila na ang bahala mag-handle ng mga complicated na bahay. Ang gagawin lang natin, is magkaroon lang kayo ng balance sa wallet, and wait.
OPTIONAL po ang pag deposit ng pera, OPTIONAL din ang pag-refer.
Makaka income pa rin kayo kahit wala kayong ilabas sa bulsa nyo. But of course, more the merrier, which I will share later.
  1. Register using the link above. You can use my referral link, or you can just register normally.
  2. Pag naka-register kana at naka-login na, punta kayo ng faucets. Makakakuha kayo ng libreng altcoins every 60 minutes.
  3. Wait and relax. Every couple hours, is magkaka "stake" or magkakakita si Coinstake. Then, magdi-distribute lang sila ng kita sa mga may balance sa particulat altcoin na yun sa website.
Madali lang, diba? So ngayon, etong altcoins na nakukuha nyo is pwede nyong i-exchange sa mga trading websites para magka BTC kayo. Then, i-withdraw nyo lang sa Coins.ph nyo na account.
---------------------------------------------
Personal experience
Hindi ko na-discover to actually. May nag-suggest lang sa akin sa Coinpot na subreddit.
For the first few days, nagtsaga lang ako sa faucets ng Coinstake. Then, I also spent time on other faucet sites and app. Nag-farm ako ng Dogecoins. Nung naka-ipon na, nag-transfer ako sa Bololex.com. 2 Altcoins ang available sa Bololex - Tokemon (TKM) and Ratcoins (RAT). So, inexchange ko lahat ng Dogecoins ko evenly to Tokemon and Ratcoinsm then inkagay ko sa Coinstake. Siguro nakabili ako ng mga 600,000 na Tokemon, and mga 1,000,000 ng Ratcoin.
Ayun, so naghintay lang ako ng 2 days, habang nagcocollect ako sa faucet. Ang TKM ko ay naging 640,000 and RAT ko naman is naging 1,070,000! Not bad for not doing anything. Sit back and relax ako, and may kita ako. Wow!
So now I invested P400 lang, and just after 4 days I manage to get approximately 0.00121647 BTC (Sa coinstake kasi, on the upper right corner, it shows an estimates value in BTC). In today value, 784.89 pesos po sya.
Screenshot Proof:
FYI, nag start pala ako mid-day ng October 12. So medyo bago rin ako, but I can personally attest na maganda tong website na to.
---------------------------------------------
Recommendations on how to cash out
Sobrang laki ng transaction fee pag nag cashout ka using BTC. Kung magca-cashout kayo, here's what I recommend.
  1. Convert nyo lahat ng Altcoins nyo into other altcoins. I recommend any of the following: Litecoin, Dogecoin, Bitcoin Cash, Ethereum.
  2. Sa na convert nyo, i-withdraw mo lahat sa Faucetpay.io
  3. Pagkalagay nyo sa Faucetpay, i-convert nto lahat to just one currency. I recommend namam yung mga sinusupport ni coins ph, which is Litecoin (LTC) or Bitcoin Cash (BCH).
  4. Pag na-credit na coinsph account mo, convert nyo na sa Pesos and kayo na bahala kung paano mag withdraw. :)
---------------------------------------------
Recommended Altcoins
Here's what I'm staking right now, since this is what I started with.
Tokemon (TKM) / Ratcoin (RAT)
Exchange website: https://bololex.com/
I highly recommend Bololex. May games din sila na you can earn what you call BOLO tokens. Pwede mong i-convert yung BOLO sa TKM, which is pang-dagdag din sa balance mo. Minimum bonus TKM you can earn using every few hours is 5000 TKM, which is not bad.
Willowcoin (WLLO) / Big Data Cash (BDCASH) / The Big Coin (BIG) / BeanCash (BITB)
Exchange website: https://www.unnamed.exchange/
Infinite Ricks (RICK)
Exchange website: https://www.altilly.com/
---------------------------------------------
Alam kong mahaba, pero salamat sa pagbabasa :)
If you enjoyed staking, you can also consider these 2 websites. Wala nga lang faucets to, so either magdedeposit kayo, or magfafarm kayo ng faucet sa ibang lugar, then transfer nyo dito.
Ref | Non-Ref - Stakecube.net
Ref | Non-Ref - Stackofstake.com (Yung ipon kong extra na Willowcoin sa Stakecoin may nilalagay din ako dito)

Screaming from the rooftops example regarding just how stupid the situation with Bitcoin is.

I've never seen this illustrated so perfectly from somebody who it is indisputable knows what he's talking about and the credentialist wannabe elitist assholes at blockstream have zero credibility opposing but just note everything about the way this question is answered regarding Bitcoin, and the way he dismisses it at the end as too depressing and embarrassing to even discuss in detail.
https://youtu.be/_L3gNaAVjQ4?t=2635
For all those that don't fully grasp just how broken the situation really is and haven't listened to those of us who have been trying to make this point for years on end, just listen to this and properly digest what it means.
This is what it's going to take for people to finally grasp just how stupid this situation is.
The entire podcast is pretty great too, but this part in particular is maybe the best example I've ever seen from a popular well known technical personality showing just how well accepted the stupidity of the core position actually is.
