Hello, if you are looking for an investment coin for 5 to 6 months, I think EXMO Coin (EXM) is very suitable for this. The coin on the British cryptocurrency exchange is doing quite well and I think it will have a big jump in price this year.
You can take a closer look at the stock exchange at https://exmo.me/en or check in https://coinmarketcap.com/currencies/exmo-coin/
