We know Bitcoin is one of the powerful and top coin in marketplace.
But world wide all county are announced its illegal.
I personally think that bitcoin is very help us for paying any payment.
Its has many facility.
But our government are announced its illegal
because in the beginning btc was used in deepweb and more for illegal transactions, such as drug sales, human trafficking, contract killers and others. so in my opinion it is only natural that the government still sees one eye and looks more at the bad side of the BTC, and according to my observation BTC is also easy to use as a means of money laundering. maybe government regulations must be even tighter in monitoring BTC so that in the future prices and the BTC community will be healthier
In addition, studies have shown that bitcoin is poorly suited for money laundering. Volatility can have too much impact on the amount. To the bad side. Therefore criminals prefer old time-tested methods. The only high-profile case of using Bitcoin for criminal purposes was the market-place "Silk Road".
