I would recommend ICX and XRP but then, you are still the right person to decide finally, we have all given suggestions, but try to do some research on which coins to divert your funds. At the long run, it's profit we look towards.
There are currently lots of altcoin for him to learn and invest. We can give suggestions so he can learn more without wasting time searching, because there are so many altcoin now. Your two altcoin are very likely to increase very well, I am also paying close attention to ICX, they are the foundation for blockchain startups in Korea.
Yes, even i am watching very closely about the ICON coin because i am filling my bags every time when the price is going down, we have seen many startup companies are launching under this blockchain will help the coin to increase the demand for this company.
