Correct, although we have reached our 10th year anniversary, crypto is still on its infancy stage so a lot of growing up pains to see and experience like hackings. It will continue though because hackers are always one step of the game.

However, I'm sure that exchanges are also evolving and trying to prevent this so called hacks to happen to them because (1) the money they invested will evaporate that quick (2) they will lose the trust of their customers, thus might go and end up bankrupt (3) restitution payment will be a headache if they don't have the money to cover for the losses.
