For 2019 I think I will have to go with XLM, XRP, TRX, DACC, ETH. This is what I am still considering to buy more of it and hope 2019 gives us the best market to swing our trades for Good.
All of them are good coins for next year according to my statistics, and I think you should pay attention to Bitcoin. It is the currency that I find very potential for next year, or buy if you can, it will give you the most unexpected results
