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?
So you mean to tell the world will be free of crime if bitcoin is banned. No never . Illegal activities, scam,
hawala etc all were there even before bitcoin . So there is no point in this. Its true that some are using bitcoin
for illegal transactions and dealings but it doesnt mean that all this happen because of bitcoin.
