If you bought bitcoin last 2010 then yes your now a millionaire if you haven't bought wait for 2018 because bitcoin will largely fall next year and then jump high by 2019.
yes I think you're a millionaire if you started or bought bitcoin years ago because the value of bitcoin increases every year right now maybe if you bought bitcoin it cost 200K something but when the time comes maybe 1 bitcoin can be 1M. and just be patient you everyone can be a millonaire only if you work hard in everything you do
