The best solution is inevitably you have to hold your ETH if you really don't need it. It is a loss if it is sold now because you buy at an expensive price at that time. One day the price of coins will definitely increase, so trust me and keep on being patient.
There is another choice - the guy can invest his Ethereum in a good ICO. However, here, he has to be very careful. The number if the fake and scam projects that invite the investors, is really great.
