Plasm token (PLM) will be used for gas, staking, governance, layer2 applications, and DApps staking. I think you all guys know the first 3 things. So let me explain layer2 app and DApps staking.
Layer2 app: When you deploy DApps on layer2, you need some PLM deposits on layer1. There are constant transactions from layer2 to layer1. Each transaction takes small fees. If the deposit becomes 0, the app will be removed. So, DApps builders have to purchase PLM token to maintain their DApps but they don’t need to pay high gas fee.
DApps staking: PLM holders can stake their PLM on popular DApps on Plasm. Then, they can get rewards from block reward. And DApps builders can get rewards as well by the nomination.
This means that the more DApps are created on Plasm, the more token will be locked. And the liquidity will be smaller. Hence, the price will be increasing if the number of DApps is increasing.
