Thanks!
That makes more sense

The whole reason I was so interested in this is because once KNC and Cointerra deliver... I was trying to figure out if the difficulty would double or triple... I think KNC is making something like 2400 machines @ 3 THs and Cointerra.. not sure.

Any guesses?

Every 10 to 15 days or so the difficulty goes up, as the new TH/s rig become available we could see time to process 2016 block increase to 7 days (say) which would force the difficulty to go up. It simply doesn't just doesn't double or triple over night, its the time that it takes for 2016 blocks to be processed.

It is a gamble - if the ship on time, great, if they are delayed, then it is terrible. Like Avalon and BFL - if BFL had delivered at then end of 2012 like they said, people who got them would've done well. Instead they were very late and Avalon shipped in early 2013 and the people who got those machines did really well.

I don't have a guess though. With the difficulty increasing so quickly you have to make the investment back very quickly or not at all.

Did you plug in the numbers to any of the mining calculators to get a guess? :-)

The difficulty isn't in terms of hashes, its just the difficulty.

The current Bitcoin network at time of this post is an estimated 11 PHash

Exactly. Salty is 100% correct.

Hash rate (approx)= 10,938,061 GH/s = 10,938 TH/s = 10.98 PHash
( = 10,938,061,000 MH/s =10,938,061,000,000 KH/s = 10,938,061,000,000,000 H/s)

Difficulty is not measured in hashes, but just is how difficult it is to find a new block compared to the easiest it could be.
(https://en.bitcoin.it/wiki/Difficulty)

The higher the hash rate, the higher the difficulty will become in order to keep the block time close to an average of 10 minutes (given the hash rate increases, the average has been well under 10 minutes/block recently which is why we see the large increases in difficulty every 2016 blocks which should be about 2 weeks, but is faster now with the new ASICs being shipped each week).

Thanks guys!

This makes it a *little* bit easier to understand... but I still dont understand it completely Huh

I guess I will have to read the technical papers to completely understand Roll Eyes

Cheers!

Difficulty is not hashes its like a notification its hardness of work and everytime bitcoin is mined and miners are more difficulties rises up. It depends on how much hassing power is used to mine bitcoin and how many bitcoin are mined, each mined block use to increase difficulty but difficulty shows latter. In normal thinking you are digging and as much as you dig its more harder and you need advanced technology to dig more or you will be able to dig little with your recent machine that is called difficulty. And your question about if you hash with full difficulty yes you wipl get 25 bitcoin every ten minute but if only you are mining but from all over the world people are mining so again you will get some share

It may be terrahashes, you should look up a table for those type of numbers.

Good question, from my understanding. The difficulty is just the numbers, it is not in KHs/MHs/GHs.

I am looking at the bitcoin calculator at:

http://bitcoinwisdom.com/bitcoin/difficulty

There it has the present difficulty listed as:
1,180,923,195

I always visit that site as it has a pretty decent prediction rate, for example it predicts the next difficulty is around 1,392,459,464.

My question is with regards to the number of the difficulty, for example the present number: 1,180,923,195 (1180923195 if we take out the commas)

Is that in Kilo hashes, Mega hashes, Giga hashes or...??

I copied and pasted the same number (1180923195) into the MHs field, then the GHs field etc and it got me even more confused.
Because, If I got the logic right then if the difficulty is 1180923195 and I have 1180923195 of the same (KHs/GHs or whatever) then I should get 25BTC every 10 mins right? But no where am I getting that answer, the closest I have come is when I paste it into the KHs box I get a return of 20.x BTC per hour.

Totally confused, would appreciate the answer.

Thanks in advance!
