Many people commit crimes by using transactions through their bitcoin goals to be difficult to trace and facilitate transactions, It makes the government difficult to formalize bitcoin because easily the crime can do a transaction but I am sure the authorities will not take silence they must have a plan to deal with all this.
Many people !, No that's absolutely wrong bro
See bitcoins can be used to fund crimes as no evidence would be present of transaction,
All we would be able to see is a wallet address and that would also be changed after the transaction automatically
People also use btc to transfer and hide their blackmoney
And by the way I don't think that the drug dealers and other criminals would go into online digital crypto currency instead they would go into old fashioned face to face transactions
We can't sblame bitcoins for these promotion of illegal things as they were there before bitcoins where even started
One of the advantages of Bitcoin is that we don't have to show our identity for any transaction, this advantage is used by them to buy drugs, weapons and fund terrorism
