Well, after a month of trying to get my (fairly trivial) bitcoins from "survey offers" and the like from these guys, I hereby declare them to be scammers.
There is no contact information.
There is no "request payment" button.
There is nothing but your balance of bitcoins earned (painfully) through "SuperRewards."
Since SuperRewards has acknowledged and paid out to betcoin.co, I can only assume that the site will hold onto them for a while and then one day close up shop, taking all of their patsies' money with them.

(there ain't no such thing as a free lunch)
Well yeah, but this isn't a free lunch.
I did some scut work, filled in surveys and the like, and the survey owners paid up--to the sponsoring site.
The sponsoring site is not paying back to the people who did the work (me).
I paid for my lunch and the sponsor (betcoin.co) is eating it. That's what bugs me.
I've all but written off my earnings. I just want to make sure everyone knows that this is a scam, and not to waste your time.
