Definitely Stratis I bought Stratis at 3k sat and it went to 460k sat max, although now is only 58k sat, it is still 50x in btc value, and 500x in fiat. Long term holding!
I definitely agree with you. I am also really optimistic on Stratis. 2018 they should have working products and beginn to operate with business customers. The recent pump was just because of the cryptohype in general.
