Darkcoin, through InstantX, allows brick and mortar shops around the world to take crypto on their own without having to get service from some foreign company that will come with a bunch of KYC requirements, and do it in a way where you can serve customers just as fast, if not faster, than with credit cards.
Absolutely - great post.
Not only that, there are millions of websites that would like to take payment for all kinds of stuff, but the barrier to adoption for credit cards is so high that they don't bother.
Look at it this way:
Q. When eMail was invented, did it kill off the post office or the amount of 'snail mail' traffic ?
A. No. What it did instead was give birth to a massive new communications medium that didn't exist before
So it is with electronic payments I think. Cryptocurrency - and especially now that one exists which can consistently confirm in under 30 seconds - will open the floodgates for a whole new economy consisting of vendors and customers who didn't have access to credit card payment gateways hitherto.
In short, Darkcoin's confirmation time is not only fast enough for bricks and mortar souvenir shops and restaurants, but also for web based sales.
