Mining is also supposed to be decentralized and yet, we see people closing down their farms...
The difference is that shutting down a mining farm or two doesn't really influence the Bitcoin network, whereas in 99.9% of DeFi, there's a small group of people behind the "DAO" that has significant control over the decision-making processes.
Sooner or later, I expect Bitcointalk to become an onion site... no more clearnet access!
I highly doubt it. The administrators of this place have been identified, as far as I know, and if bitcointalk turned into a darknet site, then the 1226 BTC in
forum reserves could be confiscated by the authorities.
