All other ethereum tokens are at an ETH loss since crowdsale (most at double-digit % ETH loss). For the people saying "just invest your fiat": you would have been better off storing your $ on the ethereum chain in the form of ETH in all other cases besides these 6 profitable tokens.
This is not surprising considering ETH returned >3000% YTD.
I just hope the Bancor team has a reasonable (not too greedy) cap in mind to give early investors an advantage, as should be imo.
