why not pps?

[nokati]

I see and read alot that for example at a pool that has an 4% fee pps  you earn less....

but when I look at the stats of the most pools that do PPLNS or other methods the luck graphic is showing arround 96% for the last 3 months for example....

What am I missing here? Basically if  you mine at a 4% pps pool or a PPLNS pool that have 96% luck history you get the same. right?

PPS pools eventually go bankrupt.  That's not good for miners nor pools.

[kano]

PPS 4% fee has an upper limit of 96% PPS payout

PPLNS N% fee has an average expected payout of (100-N+0.4)%
i.e. no upper (or lower) limit.

PPS pays independent of if you do anything useful for bitcoin.

PPLNS pays pool miners each time one of them does something useful for bitcoin.

The lower the fee on PPS the higher the risk of the pool going bankrupt - but it always has that risk.

PPLNS doesn't have that risk.

You are missing understanding BTC statistics.
Luck History has no effect on the future.
