Has the difficulty to mine bitcoins quintupled (x4) since March?

[ande85]

I remember back in March I was mining bitcoins with a XFX Force HD 7970. I think back then I was making a little over one bitcoin a week on that card, but now, using an overclocked Gigabyte HD 7950 overclocked to around 1200 (I had to send the XFX card back due to it being faulty), I am now earning roughly one bitcoin a month. Has something happened since the start of March and now, or have I completely messed up my numbers somehow?

looks that way, alot of interest in coins and mining nowadays. how about thinking quantity over quality? mining for some litecoins.

I was thinking it might be because butterfly labs said they started shipping. I read some articles that said as much, but still, you never know if what they are saying is true.

Since ASIC miners have shipped, I noticed the same.

I don't think you're off since I'm having the same issues with my GFX. From 1 a week to 1 a month.

Correct me if I'm wrong but a nomal growth in difficulty requires an exponentially larger amount of Mh/s to muster.

Being poor is never fun...being on social secuity is even worse...and here it was I was hoping to do something about my debts. Well, as long as the card pays for itself, I don't care.

*grumbles*

Anyway what ASICs are being sold? I know the difficulty is going to go up so high that even the $300 I blew on my card won't be enough to recap energy usage. Is it just butterfly labs, or is it others? Doesn't matter I guess...the time it takes to pay off what I owe, the difficulty will be astronomical.

Why don't you mine litecoins or feathercoins with that card?

USD wise, it's much more profitable ^_^

I reckon it might be because they're nowhere near as populair as BTC's yet. Also, profitability is dependant on exchange rate. And I see more future in BTC than LC's. For now.
