I think you have taken the right step. so far, I feel that there is no altcoin that is good enough to hold besides ETH. the only thing that might be good to do is to change the ETH you have into bitcoin. however, at this time ETH price increases are occurring. I would suggest holding ETH for a few months compared to holding another altcoin. however, if you feel that there is altcoin that has greater potential compared to ETH, you are free to replace the ETH that you have with these coins.
