on one hand, i love that bitcoin is traceable and the ledger is open to everyone on the blockchain to see. If i buy a ferrari, you better believe i want everyone to see that the purchase is legit and verified. On the other hand, if i want to buy drugs, id rather it not be available on the blockchain for everyone to see this transaction. It especially makes it worst if the drug dealer recieving bitcoin makes it obvious that hes a drug dealer and his transactions on the blockchain are obvious.
