you are just a kid, like 99% of Latium users, who sees this as a making money online method, and this is not the main purpose of crypto currencies. coin swap, bittrex, hitbtc + 100 more of these are know as EXCHANGE PLATFORMS!!!. So if you have some coins, doesn't matter how many, you have to try to earn money selling them and buying back again and again. There is the profit, but kids wont understand this ever.
