you have some truth to your post pooler but you might not want to compare to BTC pools as this is litecoin.
BTCGuild went PPS to make money in the long run.. simple as that
They are betting on the short blocks
BTW.. MtRed did the same.
You are right.. normally there are large fee's. But abcpool is 0% fee pps
Pool hoppers are still scarce with litecoin.. again something i would not compare just yet. In fact unless someone wrote a script its the only way to pool hop a litecoin pool at this time..
Proportional pools (including PPLNS pools) don't worry too much about these problems, because they never give away more than they earn.
This is false and mainly why i wanted to reply to your post.
http://lc.ozco.in pays out 60 ltc per block. and also
http://pool-x.eu pays 5 LTC block bonus to the block finder. Elitist Jerks use to do 50 ltc block bonus to the block finder.. so saying that a pool will never give away more then they earn is false.
Dont get me wrong I am VERY happy to see a PPS pool for Litecoin. Litecoin needs it.. I just want to make sure that when comparing other pools you are comparing Litecoin pools and not Bitcoin.
Cheers!
