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.
We could also call ETH down double digits compared to Stratis. So you would have been better off storing your ETH money in Stratis.
Just because ETH is up a lot doesnt mean that the rest is bad. Being up 10-20 times is usually considered pretty good for any investment even if others are up even more.
