so it's really only representative of solo miners, right?
i mean, how many people start their client even once a day - or once a week, for that matter?
pooled miners probably never (effectively) run it.
i've gotta think we're approaching half a million users. it just doesn't show up on this chart.
I never close mine down. Why would I? I am a pooled miner. I want my BTC in my wallet the instant a pool sends a payment, and have never had to wait more than an hour to have funds confirmed.
i'll confess that i don't understand this.
leaving your client running 24/7 is an invitation to a hack. you know -- port scanners?
and what's the difference if your pooled mining proceeds show up in your wallet more or less instantly? they're in the blockchain. that's all that matters...
i mine pooled. i open my client maybe once every two or three weeks. from the account of a separate user with an extremely restrictive firewall.
