I don't know what your financial situation is but I'm not rich, and it is extremely painful to look at ETH trading at above $3000 and realizing my rainy day fund has been stolen by criminal nincompoops.
My personal values dictate that I be significantly more careful with money when it is someone else's money. Even if you gave me $20 to get you a Burrito, I'll get you the best deal, tip the minimum, and give you your exact change. I'd even give you a few cents more just in case because I don't want to be owing you anything.
So when a group of people behaves irresponsibly with people's money it boils my blood. He deserves every jail year he got, just on the hubris alone.
