if only $ 70 was not enough to get a good coin. I think you'd better look under $ 1 but the development of the coin is very fast. pay attention and learn more details of the coin. then you will benefit. otherwise if you play on the coin $ 1- $ 5 then you get a little profit. altcoin many that I think are good, for example credits. they are stable, and prices are up from last month. try to see and take it into account.
