What happens when they flood the market with all that "free" ETH though? It's ETH that coinbase has probably held for a long time, so they probably aren't really losing any money; but if I just had the scare of my life by losing a huge investment, and then found out they were going to cover my mistake, I might withdraw some or all that money and put it somewhere safe. If even 10% of the ETH that Coinbase gives back (really, gives away) is sold, it could bring down the whole market - and all the people who didn't have risky margin trades will lose out for doing nothing wrong. And what if it's 20% or 50%?it actually penalizes those of us who didn't put in risk margin trades or stop loss orders.
