To everybody disregarding this idea, I’ll just try to clarify what the author of the post meant with “lock-up period of rebases earned”.
I see the major complaint is about the fact that the stockholder should be able to do whatever he wants to with its funds, included withdrawing immediately after having staked them.
Well, guys, I reckon the author was talking about a lock-up period for the rewards:
If you stake 1000 TIME right before a rebase happens, then a few seconds later you would have 1006.14 TIME (at current APY). If you were able to immediately sell everything, this would basically imply an “arbitrage” opportunity, i.e. a riskless profit, given that the transactions are made quickly enough that the price remained stable in those few seconds (a whale’s bot could do this, for example).
The whole idea behind the lock-up period is for the rewards, and the REWARDS ONLY, not to be claimable for a given period of time.
This means that the rebase exploiter/arbitrageur would only be able to withdraw its initial investment during the lock-up period, i.e. 1000 TIME (rather than 1006.14 TIME).
If he were to unstake before the end of the lock-up period, he would end up losing its rewards.
Otherwise, if he keeps his fund staked, they would simply continue to compound at the spot APY.
Suppose a lock-up period of 6 days (= 18 rebases). Suppose you invest 1000 TIME.
After 5 days (I chose 5 days just for conveniency, since we’re given the 5d ROI), you would have 1096.18 TIME at the current APY.
Yet you would only be able to withdraw 1000 TIME, and if you were to do it, you would lose the remaining 96.18 TIME. However, if you keep staking 1 day more, you’ll get 1116.495866.
Now, since the lock-up period ended, you are able to withdraw all your balance of 1116.495866.
Only rewards would be locked-up. You will always be able to withdraw your initial investment in TIME, no matter the lock-up period.
However, such a mechanism would prevent exploits of the rebase system by arbitrageurs, and would discourage short-term traders, so that mostly long-term investors will jump into the project (3,3 being the most beneficial strategy for the protocol, maybe along with 4,4 i.e. minting and staking bonds proceeds).
The lock-up period does not intend to impose to investors any type of restriction on their capital, but on their eligibility to rewards, and still this would be a short-term restriction that would likely benefit every holder.
[Current APY, as of December 12th 2021, has been used for computations in the example. The lenght of the lock-up period in the example is completely fictional and chosen purely for computational conveniency]
