BTW does FUN have to be locked to get bonuses or not have to be locked
Nope, FUN tokens don't need to be locked to get benefits. To quote from the freebitco.in website:
All you need to do is buy FUN tokens and hold them in your FreeBitco.in account to get the benefits. The longer you hold the tokens, the greater the benefits will be!
But if you decide to lock the tokens, you will also have the opportunity to earn up to 25% annual interest on them. However, you will not lose any of the benefits that come with Premium Membership!
