Mostly yes. If you will use it I think you will probably recieve reward in pocket tokens for staking, it might start 1000% API to attract users and then come down to 50-80% when it is established, but that only my thinking
What about staking? When it will be started? APR can be awesome at the beginning as you said.
Lots of projects are starting with high APR. The same situation was with eth 2.0. First few days APR was on 60-70% for validates but now it has decreased to 15%. Do not hesitate to join the staking first!
