If I purchase bitcoins via p2p, can I get some problems if the bitcoins I get were involved in some criminal activity ? If yes then how do I avoid such situation ?
The best way to avoid such issues is to buy bitcoin from an exchange rather than buying it from or through peer to peer, For so many years I have bought my bitcoin from an exchange that is decentralized without any issues but with exchanges going centralized this causes a major confusion, but regardless the issue of who should be added to the rebuilding and the rescue show be selected evenly
Well, if we talk about the safe place to buy Bitcoin, the use of exchange is highly advisable compared to P2P transactions. However, even if we do P2P transactions, nothing will know it was illegal and simply it can be denied by the seller that it was coming from illegal and much more if they use mixing services.
But yes, as for the comfort and to give peace of mind to OP, it was secure and to have unquestionable transactions if they use an exchange.
