Firstly Ethereum, because I can't seem to hold on to any of it. There are so many uses for it, especially for the upcoming crypto-gaming market. If I use it so much, I bet others are too, use creates demand which leads to higher value.
Secondly Spectrecoin, because of it's current btc value vs what the project offers in privacy, speed, tx costs and POS rewards w/o min staking. I have been following this one for a long time and would definitely recommend it.
