Now the price of Bitcoin and all altcoin has fallen so deep, this is a good opportunity for you to buy and hold. I recommend investing in Ethereum and Litecoin. Here are 2 valuable and potential altcoin. I believe that by the end of the year they will grow strongly and bring you a lot of profits. Especially Ethereum, this altcoin is considered the queen of the market, it is very promising, maybe last year Ethereum price will pass $ 1200.
