I don’t think your cureent earnings will be transferred. That is because the payment id and payment amount are transferred on the 1st of the following month, and since it is not the 1st of December…
Your wallet balance will be safe in Gemini though.
Also, if you’re not from the United States, you wont be able to connect to Gemini after reinstalling since that will be counted as a new installation and as of now new connections are allowed in the US only.
Don’t know if backing up the Brave folder as listed will help your situation →
I’ll tag @Saoiray @chriscat @SaltyBanana
Does current earnings also get backed up in a backup ?
