Coin buffs BOOST the rate that you earn coins while watching the stream! There are 4 slots above your wallet that can hold coin buffs so you can use up to 4 at a time! That’s right, you can stack your buffs for even faster earning! But beware, the coin buffs only increase the amount of coins you ear per minute, they don’t increase the amount of coins you can earn just for watching the stream. That’s where cap buffs come into play.
