Is Warren Buffett promoting a bitcoin promo code on TikTok?

Excuse me, but could you clarify something for me? I've been seeing some posts on social media claiming that Warren Buffett, the renowned investor, is promoting a Bitcoin promo code on TikTok. Now, I know that Mr. Buffett has been quite vocal about his skepticism towards cryptocurrencies in the past. So, I'm wondering if this is a legitimate promotion or just a hoax? Could you shed some light on this matter? I'd appreciate any insights you might have.
