Is there proof of funds or addresses we know are own by this great website Freebitco?
Concerning prove of address, I don't think there is any of such, atleast, FreeBitco have never announced any of such to the public.
And concerning addresses we know to belong to FreeBitco, I in particular have no idea of such, but I guess it won't be too hard to find if we should begin looking for that, and besides, I believe there are some of us here who must already have such address(es) handy, they can comment if they actually do have, but for me, I don't think I've ever withdrawn money from FreeBitco, so, I do not have any of their hot wallet addresses handy at the moment.
But by the way, I am curios to know why you are asking about this? For I am very sure that there is no casino that have a prove of addresses public, what exactly do you need this information for?
The thing about questioning how much they own, would be only possible if you fear not getting paid enough at all. However we are talking about a place that is around 10+ years, it is about 2013 something, we are in 2024, so maybe like 10.5 years or something like that. This is why I think it should be quite important to remember they have not really required to show their situation at all.
For a place to be required of showing it, there should be a lack of trust, when a place has paid everyone for 10.5 years, you know they can be trusted without a doubt. I hope that we could show them some respect and trust that they have deserved by being so awesome for the long time. I believe that the best thing we could do would be just a regular situation without a much trouble.
