I think now is the best time to buy Ethereum at the lowest price, especially if you have a plan to hold your ETH in the long run, prices are expected to increase very high over the next few months and years, and I remember that Eth's price is above $ 1200 only a few months ago.
buy now with the actual price, and hold it until the price rises again is really the best choice, even though we don't know exactly when exactly the price of this ETH will soar again, but I don't think it will wait any longer.
