still not with this proposal, I think an increasing reward multiplier over time is a much better incentive, and you lose the multiplier if you unstake, but unstaking is required to claim rewards. No lock.
I think locking will scare more people than it will attract since the crypto space is fast moving. The goal is to grow the protocol and the treasury and maintain maximum flexibility for participants, from my personal feeling, I feel like running away from this form of locked staking, it basically removes all flexibility and just turns the project into a "term deposit".
I have locked funds in bifrost.finance, however they provide you with a synthetic asset in exchange for ETH you get vETH in exchange, and there is a market for vETH and can be traded. As an alternative, if everybody is so fixated on locked staking, there could be a way of trading sOHM locked staking positions? Such as an NTF like Alchemist where the subscription are tied to the NFT, so you can trade the NFT and someone else gets your position. Or UNI V3 nft for example.
