of the 5 altcoins that are on your list, to be honest I would prefer polkadot as my investment asset, all the altcoins that you mention are of course good altcoins and also have a large community but to be honest now coin dot has the potential for a bigger price increase Compared to other altcoins, I am very confident that later the DOT hype will occur, so now is the perfect time to buy DOT coins at a low price and store them until the Hype Dot will occur.
