Yes of course. You can report your wished coins to us. Maybe we can accept them in the future.
Any stable coin based on Polygon or Tron network would be good. Would you implement them manually though? Because as I can see CoinGate doesn't support tokens besides the ERC20 ones.
We will see. We will discuss this with our payment provider and we try to accept more Coins during this year!
When I choose Bitcoin in Show price as, it is only has a drop down list of Bitcoin and altcoins. How about payment with Lightning network? I know your service accepts Lightning network.
Lightning for Bitcoin and Litecoin is available. At the last step, when you see the payment page, you can select Bitcoin for example and check the lightning option.
In case you need a Vietnamese translation ... I see your website has a few languages so far.
We are working on new languages. For vietnamese we don't have a timeline yet. Maybe until the end of the year.
