Ethereum price movements every day are quite large, this can be used for day trading, but in my opinion, the benefits of day trading on Ethereum require large capital.
It's not easy though, tiring and costs a lot of time to watch the market graph and planning the strategy over time based on technical and trend analysis, and don't forget the high risk to lose.
in short, day trading isn't for layman in the trading battle field. Better to buy and waiting for a week or a month to sell it.
