There's a lot of people claiming they wouldn't steal the money here.
But let's be honest. 99% of people are going to run off with the money. That's $2.9 billion right there.
There are a huge number of people living in third world countries on this forum, many of which suffer from struggles that we don't even understand.
If you're given the chance to save your family, at the expense of others, nearly everybody would do it.
The best scenario would be to just take a tiny fraction of it, such that Huobi can cover the losses—Binance SAFU fund style. This would only impact the Huobi shareholders, rather than the entire exchange userbase.
I wouldn't generalize that heavily.
Would you take the insane risk to take almost $3B out of one of the top crypto exchanges in the world and run away with it? I wouldn't. I wouldn't do it even if I was quite sure I'd do it so that I wouldn't be found out later. Besides the purely insane risk of being caught for the largest BTC heist in crypto history, karma would hit me hard as well. Definitely not worth it.
A while ago, I was asked what would I do if I knew there's a certain empty house around my city that holds $1M inside: steal it or leave it? I'd in all honesty rather choose the latter. In this case, it'd be so much more elegant, appreciated and risk-free to simply ask them for a bounty - and you wouldn't live your entire life under the constant terrorizing fear of being caught.
