A question for those with experience. I bought 30$ shib coins. The price rose by a large margin of about 250 points and I sold it. I noticed that the usdt in the wallet is 29.45000 $ . Am I wrong about something?

For your information, I bought on a limit order and sold it on a limit order as well, but I only modified the deal to close it. After the price started to drop.

I hope that the honorable brothers will inform us. Thank you in advance.

My regards
