I'm sure someone mentioned this already, but a better way to solve this would be to encourage people to actually learn and avoid using money they can't afford to lose on some random projects. Sure, it's impossible to know any exploits even if you're a skilled coder, especially when you don't know whether some employee are doing dumb things behind your back, but it should reduce the number of loses.
Even if that's the case already, it means the market is just so big that the number of funds being deposited on some random bridge is so huge that it'll attract attackers no matter what you do. At the end of the day crypto users should rely on themselves and reduce the risk of being scammed because something like this.
From another angle it just gives more room for bad actors to keep doing their thing, I don't accept what OP is saying but I think I understand what he wants, unfortunately stricter regulation will make things much worse.
There will be no more freedom and even decentralisation will struggle to function properly, everything will be monitored and that's the most hated part of this world that I hated the most.
Unfortunately there is no solution that won't have a bad side too, as per what you shared, how many people are we going to keep lecturing about crypto? Risking what they can afford to lose is good but the past so far is enough to judge this present, what have changed so far?
Nothing.
