No matter how sad it sounds, bitcoin is still used for illegal activities, especially for the sale of drugs. For drug dealers, bitcoin is a gold mine. Imagine, complete anonymity, deaf the need for meet with customers, Ah and laundering money. How to deal with it? Nobody knows. But you need to fight.
bitcoins should not be used for illegal activities. Since it is not set up, it is always an offense that people are talking about who has no idea what a bitcoin is. Actually we can not blame the bitcoin for this but the people who involve this currency for their bad deeds. But there will always be people who will use it because it is easier to send than fiat money and being anonymous will be a boon for them but then we do not can deny the fact that fiat and other payment options can be used in illegal activities as well so it should not be mutually exclusive to bitcoin or cryptocurrency so to speak.
