I recommend XRP and Cardano. Don't keep all eggs in one basket. Also my strongest recomendation and something that I really enjoy doing is looking for a new, unkown project to invest in. My current interest is a coin called BTCN. It reached CMC in a bit and it's already positioned in a couple of exchanges. The most important thing is that their development team is still extremely active and they're improving it daily plus an active communty that is building a strong support.
