Elon Musk ( Tesla CEO ), Jack Dorsey ( co-founder of Twitter ), and Cathie Wood ( CIO and CEO of Ark Investment Management ) talked about cryptocurrency at the B word conference on 22 July 2021.
Elon said that in general he supports bitcoin but worries about the publicity because of POW ( proof of work) system. Bitcoin is based on POW and it needs the energy to produce them, and doubt if it is necessary to do such a thing while it may be bad for the environment.
Elon also confirmed to the public that he only owns 2 companies which are Tesla and SpaceX. He personally holds bitcoin, ethereum and dogecoin of course.
