Bitcoin low interest. Until people will not push for its legalization, no one will raise this issue. If it is to silence the demand for legalization will disappear by itself.
We are all just fine without legalization.
I think it will even bring more problems if btc will be legalized and we may not be able to store much and the government may tax the profit we get instead of getting the whole amount into our pockets. Hope Trump will ignore the cryptos.
