Currently accounts must have 75 SP to use all of their voting power.
Update: note that the patch to 20.4 has at least temporarily eased this problem for existing users. It's unclear what the long-term intent of the developers is, however.
And that's if they do nothing else. Just fifty votes over five days will drain their RC completely.
This is not improving with time; yesterday the number was 50 SP.
As basic functionality of the blockchain remains unavailable to the majority of accounts, and this situation does not appear likely to improve, at this time I consider a roll back to version 19 the most palatable option.
Stake required per vote per day: 7.5 SP.
Stake required per post or comment per day: 40.5 SP.
This is not close to functional.
