By the way, if we gather fun tokens on freebitco, do we also get interest on them as well? and if so, the same percentage 4.08%?
According to the website, one could earn up to 25% APY on Fun tokens if he or she bought and staked it...
It's 25% but only if you lock them for the entire year (365 days):

-15 days 5%
-30 days 10%
-90 days 15%
-180 days 20%.
But I have an idea and also a question as well concerning staking for the durations you mention above and the APY percentage that comes with it.
Does it really make any sense to stake for 365 days to earn only 25% interest rate when one can actually earn up to 60% APY for the same 365 days(one year)
Now, you might want to ask how is 60% APY possible in 365 days when the site is only offering 25%?
Well, here is the answer, if staking for 90 days pays 15% APY, 90 days is equal to 3 months, and we have 12 months in a year(365 days), now, divide 12 months by 3 months(90 days), you get 4.
Now, this means that one can earn 15% APY 4 times in a year(365 days) 4 times 15% APY is 60, which means, with this formula, one can earn up to 60% APY on their staked Fun tokens by just choosing to stake them for 90 days consecutively all through the year, instead of choosing 1 year outrightly and earning just 25% APY.
How true or possible is this my formula, or calculation.?
