Yes it is great idea for supporting coin network... Bitnodes accept all currencies that coinpayments is processing and that is much more than those you mentioned. If you can make payment processor for Wordpress using EXC or convince coinpayments to accept EXC I believe Bitnodes will add it to their accepted list. Cheers!
Thanks for quick reply.
I have contacted CoinPayments a few times about EXC but this new service is more evidence as to its support and future worth.
Thank you for your hard work.
