If you want to make a profit in the future then you should invest in altcoins right now. The current market has fallen so deep, the price of most altcoin is very low, this is a good opportunity for you to buy altcoin at cheap prices. Some altcoin that I suggest you buy and hold that are Monero, Cardano, IOTA, EOS and Ethereum. These are very promising altcoin, I believe that by the end of this year they will grow strongly.
