Just one point of observation. Although I've got sympathy with people who lost money, this practice of quoting everything in fiat like the OP has done is a bit over dramatic.

Nobody forked over $270 million for anything.

If I have 1 million worthless Ether that I bought for $1, then a market trade occurs where 100 Ether are exchanged for $20 each, that suddenly values my $1 Ether at $20 Million. Doesn't mean I paid $20 million for them. I still only paid $1.

So, I say to the original poster - yes, bugs occured and people lost money, but nobody ever had $270 Million and it's disingeneous to keep quoting fiat values for anything other than notional appraisal.

An exchange rate movement is not the same thing as an actual trade so if you're being honest, the amount lost in terms of $dollar trade is very small compared with the figures you're quoting.
