Eleuthria,
I have never run PPS so it's a non event for me but it seems insane to me to have 6,200THs and have to lose sleep over getting wiped out because of bad luck.
The luck is what it is. I have been mining since late last year and have never solved a block so bad luck is a relative term. If I was solo my earnings would be 0.00
BTCThat's the thing that's hard for some people to realize. It's one of the reasons when BTC Guild became a 51% threat I tried to get people off PPS by increasing the fees. The larger the pool, the faster PPS makes you lose money, and the faster it gains money. It doesn't decrease the highs and the lows, it simply makes them alternate more frequently. It becomes a roller coaster, and the amount of stress it puts on you is immeasurable. BTC Guild, when it was pure PPS, had days where I lost over 500 BTC. It had days where I gained over 500 BTC. In the long run, it made a profit, but the human mind is designed to place more emphasis on negative events/emotions than positive ones, and every time it was on a losing streak it was nothing but stress over "something must be wrong" even though nothing had changed internally between the two spikes of good/bad luck.
Keeping PPS is something I've done because it made sense. It was more profitable for me. But these days, I'm not concerned with maximum profit but instead trying to minimize risk. My personal goal with BTC Guild has changed in the light of the non-stop "hacks" that major Bitcoin businesses claim to have happened, putting them out of business and screwing over their users. While I personally believe most of those "hacks" were not hacks at all, it doesn't change the fact that the people who paid for it in the end were users, not the owners, who made off with lots of profit over the years. In light of those events, my goals with BTC Guild have changed to make sure that if/when BTC Guild is closed down, it's on my own terms, and it's on a high note. It seems like no Bitcoin business to date has actually shut down without their users suffering some kind of loss.
PPS is in stark contrast to that goal, since it includes a risk of bankruptcy, and increased risk of loss if the pool's hot wallet ever to be compromised.
