Yeah, 60 BTC have been withdrawn from that address. I don't really think this is a 'good' sign :/ Also, the fact that we've just seen 10 more BTC after about 48 hours means, we're indeed mining with 270 TH/s on BTCGuild and the hourly payout is set for 10 BTC, at least the numbers for that scenario add up perfectly... Huh, well we'll see I guess...
