I have a 5ghz from BFL pay date aug 2012 underway soon the order had a bug but should by shipped anytime. Now lately I see auctions going up towards 25 btc. I only paid 130 euro for the machine. Even regretting that I didn't order much more. But no one expected the long wait don't we? More people want asics now then there can by produced.

Now the gold question should I sell me asic when I recieve it or hold it for mining? Like I can look diffrent ways to it. But what you should do in mine position fair answers. Do you think it can mine more then 25 btc in its lifetime?

I decided to sell mine, it went for 19 BTC on Bitmit. I'm not sure you'll get much more than that. Still, I think it may be worth it. I made either 7.5 BTC or $1900, depending on how you look at it.

Congratulations... you can make 15-20 USD a day........ Slightly more than a mexican bean farmer......

For a $180 capital outlay, with zero labor costs.

You made the right choice. Take a look at how long it would take to make $1900 mining with that rig:

Makes about 0.13 BTC a day. About every two weeks at current difficulty rate changes, you make 80% BTC/time which is probably an overestimate compared to previous difficulty. In other words think that each month will make ~2/3 the BTC made in the previous month. An infinite gemoetric series of this will say:

profit over infinite months = 3.9/(1-(2/3)) or 11.7 BTC until the 21 million cap is hit. This is also assuming no electricity costs. 11.7 BTC is only worth ~$1200 so you definitely came out ahead selling the unit instead of mining. If you can sell for >$1200 it's worth it. In fact using a finite geometric series:

3.9*(1- (2/3)^4)/(1-(2/3)) = 9.39 BTC over 4 months time so really if you can get $950 (~9.39 BTC) or more it's worth selling it. In other words I think jalapenos in hand should sell for no more than $1200 today to break even.

This of course assumes the recent rate of change of the difficulty becomes the new norm and bitcoins are ~$100 per coin but I feel these numbers are as conservative as you can get. In fact I chose (2/3) month to month change but I think it's really between (1/2) and (2/3) which means even less BTC being mined.

@OP: I'd sell if you could get 10 BTC or more for it.
