Even though the market is currently in a correction, it could be because it is in a state at the end of the week where there is a lot of selling in the market and there is a possibility that next week, the price will go up again.
But if you want to buy Ethereum, I think you can do it now while the red candle is still there and the price is correct.
Or you can wait while setting the price you want and try to place several orders at once because, who knows, the price could get a dump.
