They should concentrate on vendors who will accept ROKS for payments
Now it's better and more important to concentrate on local exchanges in the Philippines to accept ROKS. Without them, it has no sense to use ROKS for OFWs and vendors.
That's right, Rockstable project may be canceled if ROKS doesn't be listed on some local exchanges.
Or they can develop it for years and wait for the listing all this time) But I hope it won't be going on like that.
