Let's play with numbers a bit. Suppose Lykke becomes as big as Oanda. That would put its market cap at ~ $1.2 billion
One LKK would then be around $1 if the total Supply is 1,285,690,000 LKK
This is 10x its current price. I can see this becoming a reality.
The crypto world still lacks one serious (partially) decentralized exchange like this.
That's definitely a theory I've mentioned some posts ago, but you linked it to Oanda providing actual proof that is something very doable, perhaps even as soon as next year.
I also agree with you regarding the need for a trustable exchange. Lykke being semidecentralized achieves the best of both worlds, great usability and fast settlement while giving you complete peace of mind regarding your funds.
