It is a perfect solution for gaming.

Lock up some HBD in savings, earn 20%, and use the proceeds to fund some of the #Play2Earn. As popularity is achieved, and people are buying more NFTs, skins, or whatever, that money keeps getting pumped into the savings.

As it grows, so do the payouts to the players. A rather simple revenue source for the game.

I know there is at least one dApp that will be locking up a lot of HBD.

Only 1? LOL
