Wetsuit is much smarter than that.

Why would you dump a income generating business like Freebitco.in that would sustain you for years for a quick grab?
The site seems to be self sustainable and it is generating a good income for the owner, so there are no reason why the owner should dump such an asset.
He might sell the site for a large profit to someone else, if it becomes too much of a hassle.
If it too much of a hassle he gets me to deal with it

There's certainly no plan to run away, only to enhance and add to the site. It's not for sale but I guess every business has a price.
It would be interesting how people would react, if Wetsuit decided to sell Freebitco.in. The site is successful because Wetsuit built up a long-term trust relationship with a lot of users.

The fact that it has been around for many years, also give people confidence that Wetsuit would not cut and run with this. I know I will withdraw my deposit, if there are rumours of a sale of the site.

I wonder how much will a site like this be worth.
How much? I think the answer is simple:
If Wetsuit quits openly and gives time for people to withdraw BEFORE the handover, the selling price will not be good because everyone will withdraw everything if Wetsuit decides to quit. But the new buyer will still have a chance to gain trusts from the community later
If Wetsuit quits silently and announces AFTER the handover, the selling price will be better. But because it also implies that the new buyer is willing to pay more for the delayed announcement, I believe no one will trust that the new buyer won't run away
