25% out of the biggest difficulty yet is something From what i see on BitcoinWisdom it seems that we haven't reached or passed over 60k TH/s so the next difficulty jump after this one might be a very small one. Time will tell. you right if you compare biggest jumps. but history shows that 20% in real life is not that bad as later jumps are always smaller than predicted. That's because the predictions are flawed. As of now I'm showing 12.7% increase on 4/30. Average block time this difficult is 8.88 minutes. M

Bitmain just issued my coupon for a B2 unit - Ive never had issues with thier coupons (other than the seemingly random values and distribution frequency as they sometimes are not rewarded for weeks after a purchase, and othertimes only a day or two after - either way a coupon is a coupon!)
My only beef with Bitmain's coupons is that they expire too quickly (usually within a 3-4 weeks). Sometimes I just want to sit on the coupons for a bit longer, but can't. I agree, but think its totally fair that they expire. Imagine using a 0.085BTC coupon at the current price - the sale would be nearly unprofitable for Bitmain at 0.55 You think these things (S1) are expensive to make? ...

They already issued an S2 coupon to me. Are you referring to S1 or S2 coupons?

new Coupons for S1s are for recent S1 purchases. My February 2014 last purchases do not apply hence my purchase now. Waiting for new S1 coupons does not guarantee availability of S1's so it's a gamble. Good luck to you if you can get a S1 for < less than .5 BTC after coupons.

That's because the predictions are flawed. As of now I'm showing 12.7% increase on 4/30. Average block time this difficult is 8.88 minutes. M Any jump over 2-3% is bad. Imagine buying a machine for $100. With a theoretical 15% increase every jump. In the first 10 days the machine makes you $10, then days 10-20 it makes only $8.40, then days 20-30 it makes $6.70. So the first 30 days it has made you $25.10. Based on my experience the first month a miner will make 70% of its lifetime ROI if the btc price stays steady. Mining equipment prices need to drop drastically, or the price of btc must rise exponentially, unlikely. This leads to a negative standard deviation for mining right now.

If the jumps fall to 2-3% or even lower (which will happen at some point, probably sooner than most assume) then miners will return a lot less than 70% of their lifetime output in the first month. Eventually they will be more like regular computers with a ~3 year industrial lifespan.

Asic machines will be paperweights.

They're only worth a small fraction of the new value at that point, so this is a small difference.

At least good for something. What is intriguing to me is that negative outlooks and feelings of despair among miners, historically, have signaled a renewed upward trend in the price. Of course, history need not repeat itself. Just saying...

Yay for Batch 3 becoming available. Boo for pricing not being competitive with A1 options out there Guess it's more A1's for me for the next little while...

Is BTC6.5 bad investment for batch 3?
IMHO yes...not a good investment... Let's do some math... S1 is 0.831 BTC ...or $410-415 ( @112Bit as well)... S2 is generally replicated 5 x S1 ...in a rack box ...10 blades vs 2 blades design...900Gh vs 1000Gh So $410 x 5 = around $2,000 ...add 1 more blade ...around $2,100 ...all other parts, including PSU, case, LED etc are maybe another $100 at cost...$2,200...but they are saving of 4 controllers less...and they are not so cheap... My guess is that In May we will see price in the $2,000 and a change range... What do you think...? Am I missing something...? S2 is way over priced BUT saves on electricity. Still overpriced though...

Bitmain - we have had a great relationship for the past few months. Sadly, it looks like it's ending. You are no longer competitive given the S2's fragility and high price. There are better options that are built more solidly and don't cost as much. But I'll keep watching. Hopefully you come to market with a product as great as the S1's were for their time.
We just had an S2 arrive destroyed. All blades out of slots and in a bunch. It won't boot. All BITMAIN needs to do is put foam on both sides of the blade rails and on top of the main card in the middle since it's shorter. They could also Pop Rivet two flats to those rails and the sides of the case. So what the case cover sticks up a tiny bit. It's worth the peace of mind.

Look at my last posts pictures, it happens exactly the same to me. I think they should simply ship the boards out of the box in a different box than the miner box. Bitmain has offered me new blades shipping the bad ones back and they have already sent me a new card holder. So at least I got a working miner but it seems that they have been playing football with it. Not good if you plan to sell the miner to a client.
