Onion and Waves, by far. These are real coins, with HARD WORK, they have a great future and they are undervalued for now.
Be careful with coins that has nothing but marketing/speculation. Doge, for example, has no update since 2015; Tron has a code "not friendly"; Bitconnect is a pyramid scheme (actually, this is already out of the game

).
The real community (not newbies) knows exactly how to identify a good and promise coin and a shitcoin. Be careful.
