I think COSS and NCASH have a lot of room to grow. Ofcoursde EOS now is growing because of mainnet launch in June and tron is going up, but I don't have much of those. Wanchain and Ethos are two other bags I hold I am hoping will go up, as well as my small bags of ICXON and VEN.
There are just so many coins and tokens to choose from. My next pick to collect is Zilliqa, am hoping to grab a small bag of that today or tomorrow. Let's see how things go with trading.
