I suggest some altcoins i think it have potential: NEO, ADA CMT, TRX, NEM. At this time their price are low, we should buy some and hold. Maybe x2 x3 at the end of this year
Yes brother you have mentioned very good coins, but I think that among these altcoin I would like to choose ADA. I think that currently their price is trading too much low but it as still very good potential and we can in fact see a very good increase in its price in near future.
