If you operate above 5k you will have to share the profits with the lion

I started investing in crypto in February last year, without really knowing how it worked. I started investing in Brazilian brokerages, only after I found out about Binance, now I only trade here.

I often make small trades with crypto, for example, I sell BTC when it's at 95k, when it reaches 92, 93 I buy again, does anyone else do the same, or do they just leave it there?
