If they keep bleeding users like this, the website might not be around a year from now. If it still exists it will be in a crippled state similar to Bitvest. They have already shut down several sites that were failing, freedoge.co.in, xfun.casino, xfun.bet and kingdice.com. wetsuit is not like Lightlord where he will keep the site operating no matter how bad it gets.
The site is still generating good revenue as the traffic is huge. The total wagering volume is also pretty good.
At the same time, I believe it's just the beginning and the numbers will change drastically if the site keep having issues.
The number of people leaving the site will increase hugely and might have a compounding effect.
As you said, it might not take even a year for everyone to leave the site if the freebitco.in team doesn't bring it back on track.
