Now that most altcoin have a very low price, this is a good time to buy altcoins. I think it is best to buy altcoin in the top 50 coinmarketcap. Some altcoin that I will buy now are Stellar, Cardano and Monero. These are very promising altcoin, I believe they will grow and bring a lot of profit for me in the future. Especially Stellar, it has a good growth rate, I believe that by the end of this year the price of this altcoin will be very high.
