why I call it a ponzi     because late comers pay for the early adapters with their cost of bitcoin is almost nothing
in early days of bitcoin people just mine it for fun........

why I call it a bubble    have you ever seen any investment can start with almost nothing and went up all the way to over 60,000 dollar per coin  in a decade time?

even if you count it from $1 per coin  to over $60,000   that is over 6,000,000% return in investment 


what do you think?

may be it is just my silly thought....

please comment.    thank you.
