We accept Paypal and Credit/Debit Card payments via Chargebee, along with Cryptocurrency payments.
We recommend that you pay using Chargebee, as this will set up a subscription which will keep your membership valid constantly and prevent any marketplace threads from closing.
If you use bitcoin, you will have to wait for your membership to run out each year, before you can pay again. This will close your marketplace threads for the duration of time that you are not upgraded.
If you wish to pay via a Cryptocurrency, please contact support
