Someone put money on my account and bought a stock
I withdrew all my money from the account months ago but I just downloaded the app and on February, someone (I guess?) put 21,29€ in it and bought Bitcoin. I checked my bank account and 100% it wasn't me. What the fuck happened? Who gave me money and why? Is there a way to know where those money come from, like a register of deposits? Sorry, I used the app only for a while and can't find it
