You can't blame those hackers to target huge exchanges because I know they find it very irresistable. I really hope that a tighter regulation or even a government body is going to be created that will focus on hunting down these hackers and jailed for life imprisonment. And now even Binance was proven prone to hacking and the market is very healthy again, I start wondering on how much will be stolen on this year by online theft again.
I'm not sure regulation will improve anything. On one hand we've got Japan who's really gone to great lengths after Mt Gox to do right. I think they got a great model, any exchange wanting a licence in Japan's got to comply with a lot of measures, the ones I like best are the audits and the requirement to insure deposits. Mind you, this hasn't stopped the hacks from happening, but it has meant that people are protected -- assuming those insurance covers get paid out, because none of them have as far as I can tell!
On the other hand we've got Binance who's on a supposedly really great blockchain jurisdiction yet that government/regulator hasn't said a peep since Binance's hack. Strange much? I think so.
