**Project:**

Bumper protects the value of your crypto using a radically innovative DeFi protocol. Set the price you want to protect and if the market crashes, your asset will never fall below that price. Importantly, if the market pumps, your asset rises too.
DeFi Protocol for protecting assets from price drops. Protocol has two key actors - makers and takers. Makers provide liquidity to be used for protection, Takers provide assets (ether mainly) to protect. Takers pay premiums for protection, Makers receive yields (incomes) as a part of those premiums. In the event of crypto price drops, liquidity provided by makers is used to compensate takers. (Makers are bullish, Takers are bearish).
