some ppl really think cryptocurrency could some day overtake fiat or even challenge fiat the slightest bit . . . . .
ROFL! slow shitty blockchain technology can never challenge new world credit card transactions and good old cash. what mind altering drugs do u nifty boys guys take? i will be paying with my mobile phone through my bank account like 99,99999999% people of industrialized nations. "crypto"currency is NOT going to be the thing. virtual currency by visa,mastercard and co. will be the thing, digital fiat as used today. absolute nobrainer.
~CfA~
If Visa/MasterCard an Co. make their own virtual currencys, I expect for BTC to skyrocket. It would only confirm that BTC technology (blockchain etc..) is here to stay, and BTC can become a foundation stone for all these new currencies you've mentioned. BTC would maybe not be used in day to day transfers, the same as gold today. But we use fiat based on gold (so we should..), same will happen here.
I also agree, that fiat will still be here, we will not all use BTC, etc.. for daily usage, but think of what new technologies can arrive based on these inovations from BTC? The moment I saw google glasses with BTC integration, it strucked me. There is NO other way to be able to send and receive "money" faster and trustable than to use BTC or any other virtual currency. I think we're on a step on something big here, we just need a genius who's going to make something BIG + BTC. If you get me..
