Let say smaller coins like Ripple, Cardano, IOTA and ICON who's prices are currently pretty low but have large Market Cap, do they have potential to big gains in 2018? I know there will be others beside Bitcoin that can have tremendous gains? How do we look for them to have big upsides? I don't have a lot of money go for the Big price coins i can take on multiple lower end coins and purchase a big amount, would that be a good idea?
