Why are they asking you to refund the btc? that seems odd.
Was the address you emailed
support@chaturbate.com or did you reply to an email?
From the wording in that email, I dont think it's actually an email from cb support, the way it is written is very poor compared to how chaturbate normally explain things in their emails.
Crypto payouts on cb imo are one of the worst payment methods, it's like a $50 fee at the current pricing for a transaction that averages under $1
You can verify if the wallet address you were emailed belongs to chaturbate by putting your wallet address in the link i provided above, checking the sent from address and seeing if it's the same.
ETA: crypto is my favorite way to get paid and has been for a long time. Just not with cb because of their fee's
