They ran an insane, far too player friendly, NBA promo where they paid double the winnings of a selected team, that you could buy for a $500 deposit. It seemed like they badly needed money deposited fast, and this was a way to get it. As anyone with a clue could see, Players killed them on this and 1Vice ended it after about a month, even though they promised it was to be a season long promo.
Then, a couple of weeks before the Super Bowl, they stopped paying people and said they would resume 1 week after the Super Bowl. They took a YUGE position in the Super Bowl, and for the 2nd year in a row doing that, they were right when Denver beat Seattle. Still, it didn't save them, as a week later, they announced they were being "bailed out" by RDG Corp, they of the infamous Apex Sportsbook Stiff Job

When balances were transferred to the RDG Corp platform, some players were told there would be an additional 10X Roll over, even if they had already met their roll over. Some were told they were being booted and would be paid at a later date. It seems payouts have resumed for some.
That's what I've picked up from various forums. Luckily I got out of 1 Vice in the beginning of the 2015 NFL Football season, and the NBA Promo sent up red flags that made me avoid the place.
