When farming, farmers will receive a new distribution of YFBTC with every block. In the first genesis month of launch the rewards will be 0.026 YFBTC per block, divided by the proportional share of the pool.
The exception to this was the "YFBTC Party!" pool which had an additional 2x bonus.
After the first month the reward is set to drop to 0.00052(estimated) YFBTC per block which is approx 5x lesser than first genesis month.
The APY calculation is based on the return in ETH to the daily USD value, based on current block return annualized. It is not a fixed return, it is not a promised return, it is not financial advice. It is based on ETH returns.
