Is there a general rule for Bitcoin for the US? I haven't seen the topic commenting on this issue.
I think that till date there are no rules for regularization of bitcoin in the US because they also lose control of dollar not only in US but also in the whole world. Dollar is the only acceptable currency all over the world in this day and it is hard for US to let bitcoin legalize and regularize bitcoin in the currency market. Otherwise their dollar domination will dip in the ground.
