I was just pointing out the problem that even small delays in payments might have catastrophic results for users.
If said user is dumb enough to set a very high minimum payout....
I set mine to 0.5BTC. I see no reason to set it higher.
Of course if I was mining 10btc per day, I would scale that accordingly.
I have little sympathy for those using Slush to store their BTC.
Any noobs reading the above, don't forget if it's set to a too low value, say below 0.01, you may end up with a badly fragmented wallet and have to pay larger fees when you spend your coin.
