Difficulty speculations by March 1 2014

[Blazey]

the formul that I am using in my spreadsheet is:

current diff * 2^32 / 600 = hashrate

for now the formul was all time correct

so i can say only the hashrate is not growing parallel to difficulty but rather potentionaly.

i predict that the difficulty will be around 1.500 million around march or less.

The difficulty has slowed down..

Bitcoin Difficulty:   510,929,738
Estimated Next Difficulty:   607,551,779 (+18.91%)
Adjust time:   After 27 Blocks, About 3.5 hours

So for march 2014 should be around 1 billion difficulty

The difficulty now...
Bitcoin Difficulty:    609,482,679
Estimated Next Difficulty:    729,797,192 (+19.74%)
Adjust time:    After 1556 Blocks, About 9.9 days
Hashrate(?):    4,791,435 GH/s
So its gonna be over 1Billion difficulty

[ralree]

2-3 Bil is my estimate, based upon estimated ship dates of various manufacturers.

[CounterStrike]

Bitcoin Difficulty:   609,482,679
Estimated Next Difficulty:   730,105,490 (+19.79%)
Adjust time:   After 1094 Blocks, About 6.8 days
Hashrate(?):   4,913,705 GH/s

Hash continue to increase about 20%.. feel like its going to jump on the next difficulty..

[HolyTemplar]

Bitcoin Difficulty:                   707,408,283
Estimated Next Difficulty:   850,677,747 (+20.25%)
Adjust time:                   After 1458 Blocks, About 8.8 days

Looks like a whole bunch of Hardware just hit the network!

Things are only going to get worse with Cointerra planning to ship 1-2 PH/s in December

[zimmah]

between 2.6 and 5.8 billion

likely around 3 billion

Wow, note that a 20.25% increase is in 8 days.  We're only half way there which means the difficulty increase may be even higher.

Also, a 20% increase translates to a 45% monthly increase.  That's a lot more than 30%.

By March 1st (91 days) (3 more months)
Based on a monthly increase of (biweekly increase):
30(15)%  - 1.5 billion
40(18.3)% - 2 billion
50(22.5)% - 2.4 billion
60(26.5)% - 2.9 billion
70(30)% - 4.4 billion

Though it could be more than 30% increase per block.  Though I'm not sure.  This is only quantitative analysis.  I'm not really that intune with the ASIC development and release schedule.  So what are your predictions?

The numbers I produced just show the feasibility of different results.

[morrisford]

Based on the numbers I can find, the current total hash rate of the network is around 6000Ths. KnC is building 1200 Neptunes to be released in first or second quarter 2014 each with 3 Ths for a total of 3600 Ths to be added to the network. If my calcs are correct that means almost a doubling of the hash rate from one manufacturer and one batch.

Do everyone's estimates of 5 or so billion difficulty by March 1 take that into account?

There will be new hardware in the market between December and March, but after the 28nm and 20nm become standard, the old hardware will become obsolete, of the 7PH currently hashing, probably about 5PH will stop hashing soon because the electricity costs to keep them running will be too high.

On top of that, after difficulty has risen to a certain level, it will into rise exponentially anymore, at least not anywhere near the speed it did before, because the new hardware will not be as much of a leap in technology as GPU mining was compared to CPU and FPGA to GPU and ASIC to FPGA.

The new ASICs will not be several orders of magnitude better, therefore the difficulty after May or so will not increase with more than ~20% per month or so probably.

Please look at numbers before making such assumptions.
And if we cut 70% of the hashing rate wouldn't that make it profitable again for people that haven't sold their machines to mine again ?

It doesn't work that way.
Electricity cost are so low compared to the reward it's worth even now keeping your usb miner on. It's not worth buying one , but keeping one mining is.

[zhinkk]

I really think will all these shipments in Feb and March and all the new people entering the mining scene it will be around 4-5 billion.

once the difficulty reaches 5~7 billion, most hardware that is online right now will be unprofitable. They'll cost more in energy than they will gain in bitcoin. This will slow down the rise in difficulty.

I may not lower the difficulty, but it will likely slow down the increase.

Exponential growth will at some point slow down, always. And with mining, we are likely close to the point where it slows down.

like i already explained there's two factors that will slow it down somewhere during next year:

1) We already have very advanced ASICs and the market becomes more and more saturated with them, every self-respecting miner has at least 1 ASIC by march, and new technology will not bring mayor leaps, they will bring improvement obviously, but nowhere near the leaps of GPU, FPGA and first generation ASICs. And new miners won't join the market if it's not profitable.

2) Old miners will go offline because of high energy consumption compared to next generation ASICs.

[sh1k1g4m1]

If all the companies ship on the dates they claim, ~5 billion difficulty. You have to remember that come march there will be atleast 10,000TH hashing power added to the network

[BitcoinDenvini]

I hope none of them will deliver
