Hello BTC community, from computerninja

I was wondering why I couldn't post on this forum then read the newbie restrictions.

Well, I've been mining BTC since the summer of 2011. Back then, I was able to mine about .50BTC every other day (using Slush's pool). I quickly mined about 10 coins and then hung onto them until February 2012, when I sold them for about $10USD.

I was mining those on my mini-farm of a Radeon 4850 and 6950. The 4850 wasn't doing all that much, maybe 40MH/s. The 6950, about 310-325 MH/s.

I'm still using the 6950 and, have a question about difficulty. I have read some of the charts showing the exponentially rising difficulty in mining. It seems that on a pretty full day of mining (and using PC during working hours), I'm able to mine about .03BTC every other day. This is about 1/16th as much as I was mining in July 2011. Has the difficulty increased so much that this makes sense? It didn't appear to at first glance.

Any input would be greatly appreciated!

You could always try mining litecoins. Seems to be more profitable now.

I believe it has.

Everyone seems to be saying that gpus are on their way out in profitability (versus electric costs) for bitcoin mining to the like of ASICs and FPGSAs.

You might do better mining litecoins.

Ugh. I've just been mining in the BTC pool for the past 10 hours and I had the wrong username and password, over 5000 shares. I just changed my username in GUIminer. I don't suppose I'm going to get credit for the mining I've done all day, am I?
