There are quite a lot of choices and they have to be sorted so that only two remain, because currently if I look at the average price, altcoins are already in an upward position following the bitcoin trend so they have to move quickly if it looks profitable to avoid the risk of the price falling past the buying point, I prefer altcoins that move following the direction of bitcoin
Then choose SOL and LTC and be a happy hodler of them.
Some choose one, two, or ten - it's an individual preference of how many coins to hold.
And we didn't see the biggest rise of alts yet..
