Bitcoin is cryptocurrency which bring crime to growing because bitcoin cryptocurrency is anonymously and nobody cant check your bitcoin wallet so only bad news for trying to stop  crime with  a bitcoin cryptocurrency.We dont need to give any private informations to create a bitcoin wallet ,we can send bitcoin from one to another bitcoin wallet so we even dont need a bitcoin wallet for transactions.Also we can send our bitcoins directly to like example bitkonan from where we can send our bitcoins directly to our bank account.There is also other way but more expensive which I dont suggest to nobody because exhanger fees and risks in transaction like a that  and that way is to change bitcoin to paypal and nobody can also check this transaction,paypal will ask you from where are bitcoins but I heard that they can easy lie them and there will not be tracks leaved in some ilegall business.
