If this bill passes, then it means government is willing to admit bitcoin transactions are legal and subject to tax (over $600). Those who think government should ban bitcoin need to change their mind. haha...
Government major goal right now is to get rid of cash transactions which they complete have no control of. Going digital is their top priority also. It is going on in a last couple of year (a few bills attempted). Once ban on cash happens (maybe somewhere down the road), no more bank run will happen. Things are changing quickly.
Digital currency will be here to stay regardless you like it or not. It is still a question that which one government will endorse or they will create their own (creating one is very expensive). Likely accepting a popular one and put it under government control is the option.
