This does sound like a pretty attractive offer, especially considering your extensive experience in sports betting and the substantial profit sharing offered. However, to be honest, I'm personally not interested in participating. The reason is simple: it's still too risky, especially regarding my personal data and the security of my casino account. I feel more comfortable with my account being used solely by myself, thus avoiding potential problems later on. So, while the offer seems tempting, I've chosen not to participate.
Thank you for the offer.
