What will happen on BTC if the government will said that all the bitcoin holder have to pay their tax??
Maybe the expansion of BTC community will get low than usual.
Paying taxes means the government will accept Bitcoin. I think that is good, and I will volunteer to pay taxes. But in my opinion, tax exemptions for investors who have suffered losses.
The tax law changes depending on where you live but in most countries if you invest and you lose money you do not have to pay taxes on that money since you got no profits, so I suppose that the tax laws created to regulate bitcoin are going to follow a similar logic so you do not have much to worry about, just make sure you consult a lawyer in your country to be sure of what taxes you need to pay if you are a profitable investor.
