Yes it is, because every time someone deposits tokens into a liquidity pool (LP) pairing, whether using the simple mode dApp or expert mode dApp; a small percentage of the tokens deposited are taken as fees. 1% for the death pools and 2.5% for the whitelisted pools.
These fees are split three ways; 40% of the fees go towards buying back and burning the Gorples Coin, 40 % of the fees go straight to Chest, and 20% goes to the developer wallet. Every time some wants to compound their earned rewards, and redeposit into the Gorple Games, They pay the deposit fee.
The epoch system also encourages people to burn more Gorples Coin themselves as the more Gorples Coin they burn the during an epoch higher their chances of winning the current jackpot/chest.
