Im new to investing and just bought my first 300usd into btc last month. Bought at 101 and after a couple days it went to 110 and above.
Ive been noticing that since when i started, the price fluctuated a lot.

This may be a dumb question but what happens if buy at 101, sell at 102, buy at 105, sell at 107 and so on? Will the fees kill my profit? Im using binance.
