What matters is that crypto stays decentralized so it could stand the test of time. We already have decentralized exchanges, atomic swaps and even P2P trading platforms, as alternatives to existing CEXs. If CEXs fail, we can still trade our crypto in a breeze. Who knows how the future will shape the entire crypto/Blockchain industry? Just my opinion
I think cryptocurrencies are not decentralized, only a few are decentralized, and the rest are centralized. Decentralized exchanges have existed for a long time, but so far, it has not been able to compete with centralized exchanges for several reasons. And I also don't believe in the future, it can replace CEXs, very unlikely. Although many people will not like this, but CEX will never completely disappear, if Binance collapses, there will be one and many others to replace it. This is an area that makes a lot of money, I don't think people will ignore it.
