You can spend your Gulden using the Android or iOS wallet of Gulden at any Bitcoin-accepting merchant, including Steam when they decide to add Bitcoin at their checkout.
Do you have a marketing strategy in place to let people know of all the services you offer? Lots of wasted potential if you don't bring your services to a larger audience.
Is any merchants using your Nocks payment system?
Yep, Nocks Checkout is being tested at two of the existing physical Gulden merchants. I will dedicate the rest of this month to talk to the rest of the existing physical Gulden merchants to drop Litepaid and use Nocks Checkout instead.
