i think you'd better hold ETH for a long time. Bitcoin reached 20K in December 2017. the price of ETH is close to 1.5k. Recently, bitcoin prices are approaching 10K. However, the price of ether is only $200. it also has a lot of room to rise.
Early investors of ethereum now will really have lots of fun in future, I see ethereum really rising above its last ATH, because there has been lots of development on ethereum since then and after then, and even though it wasnt reflecting on it yet which was as a result of the general bear market most of the coins was in, but now that they are all in their bull run, I expect those additional features that wasnt there before to also add as booster to the price of Ethereum when the bull run fully gets to the peak.
So any investor that takes the price of ethereum now as investment pint will really be making avery wise decision.
