$BTC HELP

I bought BTC at 65k and it is now at 67k, I realized that as the graph went up I was losing money.

I am using 10x leverage and investing progressively. What's going on? Could it have been the commission for buying BTC at market price? Is it related to leverage?

I have tried searching online but I can't find the answer to my question.

THANK YOU in advance for taking your time to read me. I hope someone can help me
