I don't know anymore. Last year i took some promising small ones like Onion, Spectrecoin, WEpower, Medicalchain, but they did not impress so far. Maybe i should wait longer.
Also one that wasn't so small anymore but was very promising, SONM, also didn't explode. These were all top-rated throughout the entire community. But again, i might speak too soon and ofcourse i should hodl.
