Is there any limit on Gemini just like Uphold has limit of 4 wallets?
I think Gemini is currently accepting payments for only Publishers accounts.
You can’t verify brave browsers with Gemini.
I don’t know whether Gemini have any limit or not
Right now you can only verify as a Publisher. We will be allowing Gemini user verification soon and will have more information on limits and other specifics at that time.
