We are talking and discussing investments,trading and earning bitcoins here. For our future and earning money through bitcoin not DRUGS.
Bitcoin is a money and if we will discuss about money then we will discuss all of the things of life which anyone will buy with money. The drug is also a thing for which people use money and it is a chance that they use bitcoin for that. But if someone will use bitcoin for buying drugs then we will not blame bitcoin because the drug users will drug no matter which currency they use for it.
IT is really easy i guess to buy drug guns or anything illegal using bitcoin. Bitcoin is really anonymous and you can really make a transaction using bitcoin with having a single trase in the government so many people already using the bitcoin to illegal drugs in the silkroad and dark net.
