The invoice above is no less crazy than what Amaury and ABC are asking for from the BCH ecosystem. It is up to ABC if they want to pay me for my work promoting their product, and it is up to the BCH community if they want to pay ABC for theirs.
I suggest that both invoices should go unpaid.
If you would like to make your own invoice, here is a handy tool to do so.
The world still needs a peer to peer electronic cash system, but changing the rules mid stream and splitting the network isn't the way to get there. That's why I support Bitcoin Cash Node and I wish Amaury and ABC good luck with their new ABC coin.
BCHN it is. What ABC is implementing goes against pretty much everything we believe.
