Well, since BitZuo was on the forums but didn't respond to my post or my PM, I guess people can look it up for themselves and draw their own conclusions. I joined round 3 when the account still had more than 2 BTC in it. Paid 0.04532375, never got a single payment back. BitZuo doesn't react to my questions, so in my case it was a total scam.

Here is the transaction:

My address 1MqZ4Bivfzvhs4hXqww5sR8brWhTeB2aVG never shows up in any subsequent payments from the BitZuo account. I don't know what went wrong, but I know I'll never pay anything to him again. This site is dying anyway, as every round so far has been getting less and less payments and died out earlier than the last round.

Thanks for abusing my trust, mate.
