I would agree with Ripple and TRX, but I am not confident that this year will be a good year for altcoins.
Right now, it's better to focus on BTC as it's more volatile and we can enjoy short term profits, and that can be proven if we will look at its overall movement this year.

Altcoins is a good investment, especially the 2 that I have mentioned above, however, if altcoins won't recover, they won't grow this year and there's no certainly when they will start to rise, it's only good to buy if can hold it real long term that would not bother worrying when market remains the same.
