In my country the public interest to invest in bitcoin increases with the rise of the digital currency price. If there is a gain in the sale / purchase transaction or bitcoin investment, it is taxable income, according to the self assessment system, the taxpayer shall report the income in the annual tax return and pay the tax. and it does not matter to me.

Strong KYC during the event generates tokens will make it easier to work with banks and follow AML rules. Voluntary compliance in token sales seems to give a project a stamp of legitimacy. Many potential regulators seem to be open to token sales. preferably transparent especially when dealing with potential regulators.

In our country bitcoin is still illegal but the bitcoin sale wallet is very real no doubt

"fear" is a common thing especially in the country bitcoin is still illegal. for communities whose countries are still lay or have not legalized bitcoin then should be more careful in accessing / transactions. in the value of the economic aspect we hope our country implements a fair rule and legalizes bitcoin as a means of future transactions ..
