The first mistake I made was when the price of Bitcoin reached 109,000, I bought it at that price thinking it would rise to at least 150,000 immediately. That didn't happen, but I didn't lose hope and held onto it, and the price surpassed that high again.

I closed a long position on Bitcoin $BTC with 40x leverage, recording another loss - this time only $70.71.

Then I opened a short position on Bitcoin $BTC again, also with 40x leverage.
