Is it really over for crypto if Binance exchange or Tether go bankrupt like FTX? Can crypto survive without the centralise organizations and projects?
Just as others have commented, no it isn't over for the cryptocurency industry if those scenario you mentioned above does occur instead it'll push for more decentralization of the industry and increase awareness for the use of more of dApp instead of centralized ones. Just to take you back memory lane, back when Mt. Gox exchange was still in function and arguably more powerful than Binance, it got hacked and that didn't end the cryptocurrency movement. For more clarity read;.
The first major crypto hack occurred in 2011 when the crypto exchange Mt. Gox lost 25,000 bitcoins worth approximately $400,000. At that time, the crypto exchange was handling nearly 70% of all bitcoin transactions. The attack didn't stop and Mt. Gox was attacked again in 2014. It lost almost 650,000 of its customers' bitcoins, and around 100,000 of its own. At the time that was 7% of all bitcoins, and worth around $473 million. Initial reasons for the coins' disappearance were unclear, but later evidence showed that the coins were stolen from the company's hot wallet.
