I hope the day freebitco will shut down (hoping the day never comes any way), none of us will have money locked in there.
As mentioned earlier, we should pay attention to the October 10 date because that is the date when freebitcoin's domain registration expires. It's unlikely that they will forget to renew it, but I personally wouldn't be surprised if they don't. At least, I don't understand why the freebitcoin team is dragging their feet and hasn't done it yet.
I believe that many people have already configured their bots and are ready to pick the domain as soon as possible but as far as I know, domains don't expire immediately, they give some time for renewal even after the expiration.
Just like you, I won't be surprised if they forget to renew domain but since they have an active marketing team and rarely active Customer Support, I'm sure there is someone alive and awake in their back team and will renew the domain.
Btw there was a famous crypto casino website called safedice.io, which was very popular in old days but something happened to the owner and the team forgot to renew the domain, so someone else gained access to that domain. I wouldn't be surprised to see the same on freebitco.in
