I found this method on a different forum, and I'm posting it here after trying it myself.
This method exploits a vulnerability on Localbitcoins.com (trading website) which basically allows you to double your money (your deposit gets immediately refunded to your address, but at the same time, you also get it added to your balance on localbitcoins and then you can withdraw it again - it’s all explained in the guide)
This will surely get patched within a few days so enjoy while it still works. :hypers:
