Hi, I am interested in proof-of-stake coins.
I have researched a little about PoS and it turned out to be important to keep PoS miners actively monitoring transactions online and minting PoS blocks.

Btw, is there any way to estimate the percentage of active stakes?
I have found that PoS difficulty and netstakeweight are closely connected each other (both are shown by the commands, getdifficulty and getmininginfo respectively).
I have got the number of 343369 which is coin*day value supposedly contributing to the minting (and securing) process online.

But I could not find (or calculate) the number of total coin*day (or coin*day calculated from more-than-30-day-old coins only).
