We still have many other good projects under 0.5$,you can check on sero.cash too
Putting our money on some altcoins that have a low price is also one of the best decision to do to make a good profit, and my top 5 coins under $0.50 is trx, mwat, crypt, xrp and waves, for sure this 5 coins will help us to make good profit this year.
