There are so many good coins to hold in long term like ETH NEO . but don't spend your all the money on this because sometimes it could be risky . so invest partially and in multiple coins . do your own research before investing
I agree with you, don't spend your money in buying coins, because we don't know what the future is for all altcoint prices, and I am sure that investing in ETH is one of the right choices, because I see the ETH at the moment is very bad, and maybe in the long run ETH will start to rise again like last year.
