I fear I have done something very stupid. I got into crypto in 2017 but am a small time investor. I haven't been active since late 2022
I am getting my Laptop fixed/replaced and logged on to see my ledger holdings and delete the desktop app.
I noticed my account was about half what it should be and have an unexplained transaction of 0.22btc out of my account.
I logged on to Binance the only other place I have any serious BTC on hold and it wasnt there.

Looking again at my Ledger and transactions I think I may have transferred money from BTC to USDC in order to protect it during the bear market but forgot about it. Either that or its been stolen
I am pretty sure its the former but is there any way to check.
Either way I am down about 0.22BTC of what I should or thought I had
