I fell in love with Electra (ECA). Very cheap coin (0,005 Dollar), x10 in the last few days. You can trade it at coinsmarkets.
ECA is unbelievable fast und it's a private coin (using TOR).
In 2018 x50 is possible....if it reaches iota's marketcap now, it will be x100.

But also look for coins which are already (big) in business. Like Neo, OMG, Waves and Ark. They have much potential!
