I like the plan. Since watching many 2nd layer tokens have majority of tokens staked it appears to make the left that is circulating drop in value. I am not sure as this seems counterintuitive since lower supply should mean higher demand. But thinking deeper it maybe more related to strong hands versus weak hands. The ones who stake their tokens are the strong hands and believe in the token will prosper in the future. While the liquidity comes from mostly users who sell just for the sake of being able to do so.
Basically if there is better incentive for users to stake HBD by locking it in savings I would predict it will have a beneficial effect to lowering the price of HBD to unity. Strong hands keep their HBD while weak ones will sell them and sell them at any price, which is usually lower. (Also extending time it takes to unstake the HBD inside savings would reinforce that limitation of someone trying trade the price swings of HBD.) Thanks.
