I was buying 1 month of VPN for 5€, but it cost me almost 20€ with all fees (I think it was ethereum) 😂 monero might be better, but small crypto transactions make no sense afaik
I do not know, but anonymity costs. Bitcoin is a lot cheaper at least for small amounts (idrk how monero works so no idea for large amounts) but not anonymous and not all that fast in transactions.
It's borderline impossible to trace cash. There's a reason money laundering is pretty successful. And if you're completely paranoid, pay with coins. These will never be tracked unless you happen to commit enough serious crimes to have a team of agents track you 24/7.
Someone can not simply "install a keylogger" on any device. As log as they don't have access to the device,/you're good. They might have acces to your bank account though so they know which bank notes have been taken out of the bank by their ID. That ID can be prfectly traced if you buy in a store as that store just puts the notes back into a bank. Idk why it's so hard for you to understand that physical access to anything is a horror for anonymity. Our devices allow us to be at any place in the world and you decide to go to an ATM and your local supermarket. It's not just easier and quicker, it's also not tracable.
