I think you should invest in bitcoin and LTC. Because there are two very potential altcoins in 2018. For bitcoin you should patiently wait another 2 weeks and its price will drop to 9000 dollars. It's a great time to invest in bitcoin. LTC in April will be 30% lower than the current price and you need to invest $ 1000 in LTC. That investment strategy will get you big profits in 3 months.
