As of now, I would better invest your $1,300 into altcoins, if I were you. Bitcoin is the best choice of all cryptocurrencies but with your relatively smaller amount of investment, it would not easily double. So you better consider investing in solid yet very cheap altcoins. It is not so hard looking for them with the bullish BTC and suffering altcoins. The prices are real low. Try ETH, SC, BAT, WAVES.
