My friends... I have a note that makes me confused 😬

For example, in one of the currencies $SOL , the available balance does not match the price when selling!!

An example of this is... If I have a balance in Solana of $ 1000, when I give a sell order, the amount becomes $ 950!!!

I don't think that the trading fees are that big

When I asked the artificial intelligence this question. I got a shocking answer!! And it cannot be asked here.

My question to you is... Is this normal! Or is there manipulation in the markets
