If they could really do that for long then BTC isn’t as robust as we think. Reality wins in the end so don’t worry about what could’ve/should’ve been.

Disagree, we can learn and influence the future.
1. Too many people didn't have their own keys.
2. This led to a fraudulent exchange suppressing BTC price and pumping up shitcoins
3. It also effectively rounded the bull market and hurt BTC adoption (look at any of the cycle charts and you can see the anomaly)
Learnings are hold your own keys and help others understand why.
