I feel like I'm dreaming, is this crap for real? For how long?

[Icy-]

If this stuff is for real, I'll be able to invest around $1000 to make $1600/month?! How long will all this last? Are there any cons into this? I'm so confused as to how offering computing power is making all this money rain.. Is it hard to convert to USD?

Thanks.

difficulty will change, so keep dreaming and someone will come along to explain it much better than me

Where do you get these numbers from?

Assuming you invested $1000 in a rig and managed to somehow get 4x 5850s (they're hard to find) and managed to get it up and running this instant you'd only have 6 days left at this difficulty level, or 13.8 BTC (assuming you hopped on a lucky 0% fee pool). Next difficulty is going up about 30% (probably more) so you'll see a 75% rate of coins for the next 10-12 days. Depending on how many more people jump on board difficulty will go up again.

Bitcoin prices might rise, they might fall, who knows. There are no guarantees in this game.

Be mindful of the physical location of those 4 slots, lest you have to use risers. Make sure the power supply has enough connectors for the cards you buy. Linux is worth considering for a dedicated mining box.

You're not listening.  Difficulty will soon increase.  That's a guarantee at this point.  The forex value of Bitcoins, in US dollars, is not guaranteed.  They could go to $0 in 19 days, 7 hours.  Don't ever assume the forex will keep pace with difficulty.

That doesn't tell me WHERE you got 1623.67 from. You could have just said "83498934" for all that tells me.

Just for fun I'll show you what I mean:

4x 5830s = ~4*285 (you may get more, you may get less, this is a reasonable average) = 1140MHash/sec.
1140MHash/sec = ฿2.02 /day on a low variance, 0% fee pool with average luck. I'm going with averages here, so let's go with that.

Next difficulty increase is in ~6days, so 6days * 2.02BTC/day = 12.12BTC (if you started mining RIGHT NOW, this is optimistic as you dont even have the equipment yet)
Next difficulty projected @ 733627 (likely to be higher but this is what we have now)

1140MHash/sec @ 733627 = 1.56BTC / day
1.56BTC /day * 10 days (avg time @ difficulty lately) = 15.6 BTC

Next difficulty could be whatever, lets go with 30% again
1140Mhash/sec @ 953715 = 1.2BTC /day x 10 days = 12BTC

12.1 + 15.6 + 12 = 39.6 for a 26 day window (close enough to a month). Assuming coins to be @ $35/coin (could be more, could be less) x 40 coins = $1400. If coins are $45 you make $1800 if coins are $5 you make $200.

This is an optimistic guess assuming lots of stuff goes your way and you can your rig up and running today but it can give you a feel for your diminishing profits and variability based on coin price.

Ok, well I guess if a webpage said it then it must be true.

I want to punch you. That is all.

[Jack of Diamonds]

Go to http://www.alloscomp.com/bitcoin/calculator.php and enter 1000000 as the difficulty. That's what you will be mining at in 2-3 weeks. Then roughly 2 weeks after that 1300000 etc.

You gotta be careful with those month long predictions. I thought I was going to be pulling in shit gallons of bitcoins a month. Turns out I'm only pulling in a couple poopoo pints here and there. It's badass, but you're not going to get the amount of coin you're thinking. Then again, the price could shoot up and it wouldn't matter.

I was expecting 150 coins a month when they were at $6, ended up getting 35 coins, but now they're 30. So basically you're buying a mining rig to speculate.

http://bitcoinx.com/profit/index.php is wrong in so many ways it should be shutdown. As it simply Does Not account for any difficulty increases AT ALL.

That one has been a issue for beginners for a long time now now by giving out false earning values.

[iMiner]

But by mining you kind of buy insurance against a fall in bitcoin value, considering the (historically) strong correlation between price and difficulty (but of course: historic results...no guarantees....etc.)

That's how we initiate around here.

You passed.

The correlation is that newcomers buy up coins, price goes up, kiddies run out and buy as much hardware as they can.  Since Bitcoin has no utility yet (except for criminals or people who want to make micropayments without fees), it's essentially nothing more than a glorified ponzi scheme - the machine needs new entrants (investors) to keep the scheme running, otherwise it fizzles out and dies.  Though I do hope it becomes much more than that, because the ideas behind it are revolutionary.

Exactly that may turn out to be an important detail.

I am confused by these two statements. You say it is a ponzi scheme but how is that revolutionary?

It's BitSpeak, welcome to the Brave New World.   
Currently Bitcoin has many similarities to a brilliant Ponzi scheme. If the BTC economy and general usage grows fast enough, then it will be  revolutionary.

You clearly missed the part where I stated the _ideas_ are revolutionary.  I was referring to the design from a technical and logical standpoint.
