Among the things within their control, the only major fault I see is failing to maintain a strong presence in the online poker community. If I was offering more game formats than any other site and had the lowest rake around, I'd be shouting it from the rooftop. High miners' fees, which are out of their control, may prompt them to reconsider accepting other crypto. The BTC-only thing was fine for a while, but is now holding them back.
They said they were going to change the way krill are awarded under the new system. They haven't done that, so they currently have a VIP program that's not worth much.
They said they were going to support the Bitcoin Gold fork. They haven't done that. You might want to check how much the BTG they're holding for you is worth.
They continually remove/reduce krillrolls and guarantee tournaments with no explanation and no warning. They have the resources to continually futz with the tournament schedule and yet every change they make is negative.
They said they were going to have more of a promotional presence in 2018, instead they've completely vanished.
I'm not as negative as DarkDays but I'm also not interested in redepositing on the site, or holding any money there, under the current state of play.
