I can only recommend the coins that I was hodling. That will be XRP, Cardano and Ethereum. I bought Ethereum below $100 USD and I am aiming for short term trade. For XRP and Cardano, I am planning to hodl it until their price pump. It still depend on how my Ethereum coins goes. If it goes well, I can hold the other coins for a year (best case scenario). Hopefully things will work well by 2019.
