This question doesn`t have one answer, I`m staring in all this answers, predictions, wishes, and in this topic, and there is so much of everything. I believe in changes, system we have now is very old one, and I expect changes to come. Bitcoin have a good structure, and it seems like bitcoin have advantages over fiat. That is not enough for one currency to get to the top, in end we as people decide what will adopt or not.
   I support bitcoin, and for that reason I would like to see bitcoin as future of money. Just for that bitcoin will need many supporters, and in case that people start to like bitcoin as something new and better then everything else, expansion and taking primate will be easy task for bitcoin as currency.
