I think Freebitco is available for all the countries, and if gambling is banned in your country then use a VPN to use the site. Also I don’t think that they’ll disclose where they operate from due to safety concerns, and I personally feel that they’re safe so you can store your coins with them.
Maybe year or two ago I remember that I saw information where Freebitco.in is registered, but now I can't find it. I remember it's not Curacao, but one these offshore countries. Though, country where they are registered and country where they operate is 2 different thing. I may be wrong, but I predict that wetsuit is from US.
Congrats! 5000 tickets is nice number. Good luck on Sunday lottery draw.
