I have been using crypto since 2017, made plenty of dumb trades which caused me to lose out a lot. Currently my portfolio is about 80% BTC and while the new USA admin seems they may do more damage than good to the crypto space I’m still positive about Bitcoin.
This sub seems like a meme or anti-btc sub mostly. Anybody here who isn’t that way?
Sure, those attacks happened on lesser-known chains like Ethereum Classic and Bitcoin Gold, but doesn’t that actually suggest PoS is more resilient in practice, even if can be argued that it’s weaker in theory?
In PoS, to extract value or compromise finality, an attacker needs to control 67% of the stake, which has never successfully happened, even on unknown tokens or forks from popular chains. That’s a pretty strong track record for security and resilience.
The lack of successful 67% attacks on major PoS chains is indeed a positive sign. However, this could also reflect social deterrence, early-stage economics, or insufficient adversarial incentives — not necessarily intrinsic robustness.
Anyway my initial argument was that Bitcoin have no interest to move away from its PoW and especially not to transition to PoS. PoW isn’t perfect and has its drawbacks but PoS is not a better system, it’s an alternative with other drawbacks that doesn’t meet every chains needs.
True, I agree that PoS has tradeoffs and isn’t a perfect solution. And I totally understand that Bitcoin has lots of reasons to stick with PoW. I was speaking more generally about resilience and security in PoW vs. PoS.
I don’t think what happened to Ethereum is a fair comparison, because PoW doesn’t have finality to begin with. When Ethereum temporarily lost finality, it just reverted to a PoW-like model, where finality is probabilistic. It was a degradation, not a catastrophic failure.
