Ethereum is the second best cryptocurrency. It has proven to be a solid and trustworthy coin.
It's hard to predict when the price will peak again.
I think it will take a few more years for ETH to return to the ATH, but overall, this coin is still very potential for you to choose a long-term investment. In fact, holding ETH requires a reasonable investment strategy, and you need a lot of patience because this market is no longer the same as before. In addition, you should also invest some new coins because these coins are worth your long-term investment.
