My apologies for the delay in answering - the world has been a little topsy turvy.
The watch Dog status is temporary its a notification that our mining pools all went down at the same time - it will not affect your rewards and as long as you are getting rewards you are contributing to the network.
Thank you for your continued support and let me know if there is anything else I can do to assist.
In answer to your question regarding the Exchange - we have waited to see what is happening here as alot of them are closing due to the KYC requirements. Many of them accept your deposit to list but don't tell you they closing and so its a bit dicey at the moment to pay over to exchanges when we not sure they going to stay. The other concern is tiny exchanges that have just popped up and have no backing yet which is also a risk - we will monitor this closely and decide on an exchange when we are sure its a value for money easy to use exchange partner
As for the payment gateway - we are talking to potential partners to use the Gateway but we also use it already on our own site. The main reason for the gateway is so that ANYONE can use it and if you are an Arion supporter and own a website the idea is to use it our selves and provide goods and servioces and accept Arion as payment . That helps to create an infrastructure that everyone can use

If you need any stickers or material to say you accept Arion you can just ask we happy to assist
Kind regards
Nikita
