They are very good investment choices indeed but I think the op means the coin which are even cheaper than that. Let's admit, they both have already experienced their  big growth of price. That's why I would suggest dogecoin. It is currently #21 in marketcap, although it is worth a couple of cents. Furthermore, it has a very secure code, fast transactions and second biggest cryptocurrency community after bitcoin. I believe this one can raise in price and bring you the money.
