It is true that there is no need to doubt it because for long-term investment Ethereum is a safe choice,
so no need to worry when holding it in the long run,
until now Ethereum is still the king of altcoins.
ETH is still known as the king of alts because of its ranking in the market and despite that many other altcoins that are being said to have better networks, still remain the top choice of the many. I still also hold ETH and they're just a few of it and hoping that in the next bull run, I'll dispose of them and sell them so that I'll get a decent profit. But from there, I will not hold eth anymore as those are like the few ETHs that I'm holding ever since so it is like a make it or break it for me.
