If we want to make more profit then we have to take risks. cryptocurrency is a new market, it has great potential, but this market is a lot of risk. If we know wise investing in altcoin then I believe we will have a lot of profit. At present, the price of the market has fallen dramatically. All altcoin are priced very low. I think this is a good time to buy altcoin. We should buy altcoin in the top 50 coinmarketcap. Some of the altcoin that I think have growth potential are Ethereum, NEO, Cardano, IOTA and Monero.
