Our problem is that if we do not speak up for bitcoin then someone else will. Someone less qualified and with their own agenda. So if you do not like regulation then now is the time to contact your senator. This is a YOU job!
I guess the Senate banking committe aimed to be misled, so there is no doubt why they invited this person. This way, the commitee will have an excuse if ever they decided to implement regulation that is hostile to the crypto community.. They will just say, it is an advise of this "expert" in crypto industry.
