What do you mean under $10? The list is erroneous. Waves is already more than $10. So is Strat and Lisk. These are already more than $10 in their prices. But one or two months ago, they are cheaper than $10. If you want really cheap coins, even under $5, then go for POWR, AVT, Siacoin, BAT, Dent, and IOTA. There is a very bright future to all these cheap coins. It is easy for these coins to multiply in value.
