Prizedice made me deposit more crypto to claim a fake $5,000 prize

A fake account pretending to be one of my YouTube subscribers told me I had won a $5,000 drawing. The money appeared in an account connected to Prizedice.com, and I was told I could withdraw it immediately.

The withdrawal story changed as soon as I tried to access the balance. I was told to deposit $100 in crypto, then another $200 to verify ownership of my wallet. After that, I was told there was a so-called VIP error and that I would need to deposit a total of $1,200 before I could receive anything. I lost $300 before recognizing that the supposed prize was being used to demand more deposits.
