there are no 'the best' altcoin.
because every altcoin have its momentum and we can not just trade one altcoin.
of course people will recommend you to trade x coin or something like that other than an ICOs.
but nobody know which one is the best,
just trade the top 5,because if you want to get profit you need to find a coin that has a lot of volume.
Such a good advice.
and indeed nothing is best.
i did many trade (by some money) but i didn't always get success.
that's why im here for ask some opinion.
