Is FUN already been accepted on gambling sites other than freebitcoin?
Not the right thread to ask this question, you should direct this question to FUN's team instead
And when they are already available on exchanges, why would I buy them at freebitcoin? Is there anything out of the box being offered to us to pay for a specified lot?
There was 1% discount until 5th February if you purchase it directly from the site. Also to receive the benefit of FUN in freebitco.in, you need to hold those token for atleast 30 days but freebitco.in hasnt enable FUN deposit yet so even if you buy your FUN token on exchange, there is no way for you to transfer it into freebitco.in
If you want to enjoy the early perks of those tokens after the launch date then you need to purchase it directly on the site
