I've talked to the team of directbet regarding the cap of his site, He said there was another interest. In my mind maybe directbet there is a team problem that splits them into a mess.Because when directbet said it would close, michelle aka directdice time was not on for 6 days ,A long time, he is a very active cs at here.When I'm pm about to open again, directbet says there are no plans to reopen.
Rollin.io I think their users are reduced so they sell the site

What exactly is happening on the gambling site?
Does not the gambling site give big profitable to the developer?
if the developer will continue to get the profit from a gambling site, then why did they shut down the effort that has been built since long?
What happens is the strongest that will last. Gambling sites provide only a few percent for developers, they also have to deposit the profit to the owner. He does not work alone.

just my opinion
