I am always a fan of Bitcoin and Monero. People can track your identities easily through "blockchain" if you use bitcoin to buy and sell. It's so called "pseudo-anonymous".
To be honest, Bitcoin is not designed to help hiding illegal activities.
Instead, if you use "Monero", which is not traceable inherently, no one can trace your money.
"Monero" is the only altcoin that is not traceable, inherently. That is, no open blockchain.
If you have any question, you can ask /r/monero for help. That community has a large user base and is so kind always.
"Lovebitcoin" you sure about that?
