The government collecting taxes would be good for Bitcoin and users would be able to use it anywhere as legal money. Since the government can benefit from Bitcoin, it won't take long for Bitcoin to become legal in many countries worldwide because if they don't make it legal, they won't be able to collect taxes either.

They are not taking taxes from every trade you make. Instead they will take 10 percent of your yearly profit. If your profit is very low or you make a loss they won't take anything. Suppose I make $10,000 in profit in a year, I would definitely be willing to pay $1,000 in taxes.

I know if I only had to pay 10% in taxes I would be tickled pink...  Last year I paid a significantly higher tax rate than that and a 10% rate on Bitcoin gains would have saved me hundreds of thousands of dollars in taxes last year alone.  It is getting harder and hard to justify being an American citizen these days.  I really hope something changes and we don't keep raising taxes to pay for our country to be invaded and conquered.  Unfortunately, we seem to have a political party that is set on following Europe's playbook.

The government can knw that you own or purchased some Bitcoin when you keep them on centralized exchanges or wallets or you use them to  buy and sell when you want to do some transactions. They can ask those exchanges to take the taxes directly from your transactions hence if the government want to be very strict on taxing those that own Bitcoin, they can do it with exchangea that are under their regulations.

Do not be happy that Bitcoin is not famous yet in your country because your country is missing out if that is the situation over there, if there is anything that you can do to make Bitcoin popular do it so as to bring awareness to the citizens of your country. Do not be afraid about the government taxing you guys as still Bitcoin becoming popular is going to benefit you guys than the taxes that the government will want to take from you guys.
