I think that bitcoin will not grow like before x20 i think that growing will be much slower maybe 15-25% per 3 months because bitcoin first must become more popular than paypal to grow 20x.
i think people before thought that bitcoin cannot grow from 10 dollars to 600 too, and i think that right now still everything is possible and i hope that it will make me big money, i hope such price will be reached in like a year
