Obviously worth, if you buy altcoin under $1 it is very profitable. If you follow the coin price and you can see under $1 price is growing very faster. Under $1 coin don't dump very soon but if you can possible to overcome and it can reach above $1 so you can buy altcoin under $1. At the moment I am by some Bob and CJT coin because this coin value is below $1 and I hope it is growing very faster.
