For me, HODL is becoming a big meme. Try to ride the waves on good solid coins. The main ones that seemed to show promise are the ICOs with great organisation and idea, as opposed to the best marketing strategy. ICOs like Rentberry bring the ideas of long-term leasing to the blockchain and MeVu brings the idea of a great compliant exchange with a new idea in this blockchain trading scene with wagering.
It seems to me that due to the current state of the cryptocurrency market, it is impossible to make predictions about any projects with such a large growth rate. Although If you pay attention to the tenfold volume of the cryptocurrency market, you can expect the same growth after the stabilization of the market.
