Hiya,
If you open a Bitcoin wallet and receive money by Bitcoin, can Bitcoin payment trace back to you and auth0rity or popo can find who received this money? What if they pay you a test money to be able to trace it back to you and find you?
How they can trace you in darknet?
Can vpn provider send the auth0rity his clients logs, while they claimed they don’t keep any logs? Could you sue the vpn company as they breach the confidentiality policy and agreement, if this happens?
I just wondering how to be safe! 
Thnx
