As for me, I think not to buy only 1 coin/token. You should make some difference. 70% in a 5 coins, and 25% for example in some ICOs. For me I left 5% for different games. Such as CryptoKittys. Right now I find CryptoCup ( I very like footbal ) - https://cryptocup.io/landing
So, I'm more than sure. That I'll get a big profit!
