PPLNS is SUICIDE.......One bad block (300% or more) can kill MONTHS of your earnings... and you get ZERO ramp down..and it happens OFTEN.
It happened EVERYTIME I got SUCKED IN to their CULT...and I have HUGE regrets for swallowing their MISLEADING INFO.
I had 27 S9's for just over 360Th (24 1/3 survive but are mining at a loss now)

Oh you also can get sweet fuck all during your ramp up

And then some whale comes in with 200P to get a block but pushes out all your shares value..Again diminished returns
And the Whale also gets a BONUS!!!

I was a fan of small pools and tried to support both Kano & C.K. but took HUGE losses due to PPLNS system
(I even bought 2 Sia Asic's and 2 Decred Asic's from C.K. for 14K CDN and made ZERO from them before they were obsolete)
I STILL have a payout outstanding from CK's pool but have not submitted shares since LAST NOVEMBER.
His pool has not found a block in many months MEANWHILE the diff has readjusted 8-9  times. AND went up an insane amount.
So while the pool advertises it is at 167% it is  really MANY times worse...My expected payout is actually now about 35% of what it should have been if a block had been found at 100% MANY MONTHS ago.
PPLNS IS A PONZI scheme for the early hard core with a good amount of rate/gear..but suicide for late comers and infrequent hashers/suckers.

Kano's recent hot streak will never come close to making up for the MASSIVE losses sustained during the cold spell that occurred AT A MUCH LOWER DIFF!!! DIFF = TIME= LOSS
They don't/won't tell that a 5% variance on a LOW diff is QUICK and MUCH less of a loss compared to 5% variance AFTER A 50% DIFF INCREASE
Likewise an EARLY 10% block still yields a pitiful payout when the shares are assigned to a block after a few diff increases.

PPLNS is a SYSTEM that BY DESIGN makes your shares EARN FAR LESS by DELAYING them. You are effectively taking yourself OUT of the competition.
