Providing liquidity on BUSTA FARM for yield is a large part of the ecosystem. When an affiliate brings on a friend who earns yield in a BUST pool, the affiliate profits as well. At the time that the friend claims rewards, 5% of the claimed amount is also given to the affiliate to collect. This 5% is taken out of a special affiliate reward pool instead of out of the friend's rewards, so the affiliate gains the extra tokens without the friend losing anything.
