I wish BTC is not used for illegal activities though it is a currency. Legal and illegal activities require money. It depends on who uses the coins. Lets utilize the bitcoins only for good purposes as it was created to benefit all and lets bring more fame and name to bitcoins and its founders.
With the anonymous factor and descentralized factor? I believe bitcoin was created for ilegal propouses or at least a lot of transactions are linked with something ilegal, we can't stop it and that's why bitcoin have this price.
What are you talking about? Bitcoin was not created to conduct illegal activities, bitcoin was created so we could get our power back and away from governments and banks that have monopolized money.
