You can try to invest some of your money to bitcoin also because we all know that even though the price of bitcoin is going up or down, its price is easy to recover as time goes by so I would suggest that invest some of your money into it. Also, you can try the ETH and Ripple because they are the most trusted coins as of now based on the ranking system of the market.
if I were him, I might have invested 50 to 70% of the assets I owned into bitcoin. the rest are ethereum and BCH. the price increases that occur prove that bitcoin is really worth taking precedence over other assets. maybe investing in altcoin is quite profitable when the price goes up, but the potential for very high increases is in bitcoin.
