With cryptocurrencies like Nano out there, I don't think LinxPay even has a chance. I don't think they can compete with something that is Instant and Fee less. Plus, Nano has a big and active community which is currently growing really fast.
It's totally depend on the mainstream adoption.
Blockchain projects won't success without a real world use and most user friendly project will take the lead one day.
And soon we all find out which will take the lead.
Cheers.
