Well, poloniex ETH/BTC is the main market. So i assume most of this ICO ETH would go through bitcoin part... So i got scared...
Have you tried to withdraw a significant amount from Poloniex recently? No one's getting their limits raised and there are withdrawals frozen for quite a few punters. They've really shat the bed recently.
If I was something to do with ETH I would've done everything I could to move the market away from there.
I'm sure they'll shit on normal punters and even pull moderators from the trollbox to support a good fraction of an ICO like bancor. I'm completely blind to the notion that a Swiss foundation that is going through such an elaborate and incorporated offering offering will proxy their cash-in via a personal polo account opened via the website.
ETA: looks like it is coinbase shitting the bed at the moment though, see
