To be honest, seeing the price increase helped me assure that they weren't going for a Ponzi scheme. I figured they had costs go up, so they raised prices to alleviate it. By the time I met my minimum for another order, the hashrate went down. Squeezed an extra 4GH/s, woo!
I'm starting to see an increasing number of referral awards, which is making me quite happy because it's bolstering how fast I get another upgrade. Yes, don't put all your eggs in one basket. But at this point in time, I'd made back the fiat costs and am just reinvesting what I earned in Bitcoin. Once I reach a certain level of output from BCS, I'll likely use future purchases to send to Cryptsy, where they have mining shares and just keep going round and round like that, spreading out and building up. But I'm liking BCS' pricing and policies, so I can't complain.
