Very funny.

I have been mining STR (almost) from the beginning.
Better get familiar with the history of this coin.
A few days ago, I have been able to prove the instability of the staking-algo (read my post).
This is also, I believe, what happened to the POS block generation in late 2013. It simply stopped.
Time to abandon staking completely. Just go POW.
BTW, there is no option 'staking=0.'
