Right now, crypto is not really used in the daily life of most people.
OmiseGo has the potential to be the very first technology to change this and become the PayPal of the blockchain world.
There are no other technologies in sight which are capable of doing this.
The most valuable asset of OmiseGo is it's promise to deliver a white-label payment solution for paying customers.
This means corporations like Starbucks can rename it to "Starbucks Pay" and the average consumer won't even notice he uses blockchain technology while paying.
Big corporations will offer OMG payments beginning in Asia and eventually in western countries, to profit of its cheaper processing fees, faster transactions (+ refunds!) and lower maintenance costs (no terminals), while minimizing risk of fraud and mainframe downtimes by Vista/MasterCard. Some Asian countries where the application of bank accounts is afflicted with numerous barriers, OMG could be adopted very fast.
And there is another possible feature: FacePay.
If OmiseGo will really be the technology behind this, you can expect worldwide adoption and big marketing.
Why did OMG rise so fast?
-> Backing by Vitalik
-> Announcement of partnerships in Q4 and app launch
-> Rumors of partnering with McDonald's Thailand
-> Supporting Plasma network
-> POS/Airdrops
