In Korea, they use T-Money everywhere. For travel, bus, subway, train, buying food in convenience stores, stamps, post office, police station, delivery, parcel, tickets. T-Money is their contactless debit card that everyone has. Some even have several.
Bithumb and other Korean exchanges seem to have the highest traded value for Dash.
With Dash governance, and budget, they can set forth outright in Korea. Translate, let them use, within minutes they will be swimming in water like fishes. Because of the fact of T-Money. They are mighty comfortable which this style of technology.
I can see Koreans using Dash for buying coffee (if the coffee shop is onboard), settling tips among friends, paying for a service, parents sending to kids for the pocket money or school, school trips.
I like Dash, I like Max Keiser. Just Dash might have overlooked Asia. Just take a peek to Asia. Assuming easily it can go forward in Korea, I am positive it will catch on like wildfire like Kpop, Gangnam Style and Twice.
