Google Glass is revolutionary.. why exactly? I can do everything it can with my smartphone, and not look like a jerk with sci fi goggles on everywhere I go. Google Glass "solved" a problem that nobody had of wearing a computer on their faces at all times.
Likewise, bitcoin doesn't solve any problems for people, and actually opens the door to many new problems and vulnerabilities. That's why it failed! Six years after its creation and it still has less users than the frequent flyer club of Kuwaiti Airlines.
You may be speaking for yourself, but not for me. Bitcoin is the cheapest, fastest, and most secure way to move money. I use it for all my online purchases and will never go back. I have gone through three shitty bank cards in the last year. They are not safe enough for me to use anymore. I have never lost a penny of BTC. I don't really care who else uses it, I use it because it has solved my problems with buying online and in foreign countries.
I don't know where you got your info about the Kuwait frequent fliers. But Tony at BitPay has like 40k in business customers and Coinbase has about the same. There must be a few hundred thousand individual users also.
I pay with my credit card and actually get cash back (up to 6%). So yes, maybe for
you bitcoin is the cheapest method to move money, but only because you have no idea what you're doing.
I used bitcoin once for a purchase on newegg and saw first hand how bad it is. First, you only get 15 minutes to make the payment or the price could flucuate and you need to request another order. Then, you're given no warranty from a CC company or similar institution and in the case of a refund, all you would get is store credit. Nobody in their right mind would see that as an improvement over the current system.
