In Bitcoin-based transactions, about 76 billion US dollars of transactions are involved in illegal activities each year, accounting for about 46% of the total Bitcoin transactions. Almost a quarter of bitcoin users, and nearly half of bitcoin transactions, are illegal. Therefore, from a quantitative point of view, the use of Bitcoin is enough to become the target of attention of governments and international criminal police. If governments block Bitcoin, does Bitcoin have no value?
To be honest these numbers don't make any sense because first of all how will anyone know what the transactions are used for, the government has no control or a way to monitors the bitcoin transactions and track the bad ones from the good ones, and the truth is you can't blame bitcoin for people using it for the wrong purpose, with every thing you will find people that abuse it, and if it was the case money has been used for decades for drugs murder and all the bad stuff, instead of banning it governments could use it for their own good to catch criminals, since it totally anonymous for the criminals it is anonymous to the governments as well.
