What is it?
Basically a virtual Contactless card that you have on your phone and pay anything with bitcoin. Every transaction creates a coin[PLU] that has some value and can be used to pay stuff down the line. In other words...some sort of VISA KILLER.
EDGELESS

Tagline: The Ethereum smart contract-based Casino offers a 0% house edge and solves the casino transparency question once and for all.
What is it?
Online casino killer, of course. Why pay high fees, and feed the house of online casinos with their unholy edge? No more! The blockchain can make it almost edgeless. If it will, it threatens to take over a market that is worth tens of Billions.
GOLEM
