Freebitcoin doesn't have a Curacao gaming license so they don't have to restrict countries from using their site. Therefore anyone can use it without breaking any terms and conditions. Just remember that using a VPN on a site without a license =\= breaching their terms unless they specifically say so.
The reason why they do not have curacao license could be known or unknown but I feel like they are more trustworthy than whoever gives curacao licenses don't you think? I mean we know freebitco.in here and very well, thequin is here all the time and talks to us, we also have wetsuite who was here all the God damn time every single day, kudos to him for grinding sooooo hard on early days, he deserved to own such a company, so all in all we all like them, but even if you somehow hate them, you at least know them for sure.
But what about curacao? Who do you know from there? Who gives the licenses? Which branch of government or maybe private? How much does it cost? Maybe I can just pay 2x and get a license while being a scammer? I have zero clue about how curacao works, hence I think freebitco.in is 100% more trustworthy than the curacao license brand if you ask me.
