FREQUENTLY ASKED QUESTIONS

Q.1	WHY USE THIS VAULT?
	Ans	Most of the popular vaults' owners can switch "strategy" and steal (a.k.a. hard-rug) your valuable assets.
		Granaries or Kompound Protocol cannot change its own behaviour or strategy once its deployed on-chain.
		Our code uses unchangeable constants for tokens and external contracts. All fees & incentives are capped.
			Unlike the other (you-know-who) famous vaults.

Q.2 WHAT IS ELITENESS?
	Ans	Simply holding ELITE (ftm.guru) token in your wallet ascribes you Eliteness.
		It is required to earn worker incentives from this Granary.
		Deposits incur nil fee if the user posseses adequate eliteness.
		 	ELITE has a fixed supply of 250.
