Investment with the time you are targeting 1-2 years, you can choose ETH, Ripple, NEO, LTC, and ADA. You can continue to monitor the prices on the market in order to take the right time, with such a long period of time, I think you've gained a considerable profit.
I agree with Ethereum, Neo, Carsano. I also want to add to the list Zilliqa and Wanchain.
I find that XRP is good for long-term investment why do not you choose it. There are also some coins like XVG, TRX which are low value coins and also have good growth potential.
