 Is English your native tongue?  If not, perhaps you could write this post in your native tongue.  If I can't understand it, I have a friend who will.
If English is your native tongue, please don't say anything else.  I will simply concede my prize.

Cross check your eqn. & eqv. don't you think you omitted something or made mistake when cross you cross-multiply and made subject  BTC^x to BTC^y ?




Thanks

Shit, back in the day I would've calculated for fun the freezing of water from X^o given the same parameters, but now I'm mostly at a lost as to what the fuck you just did. But, give me a couple hours, and I believe I could be up to speed once again.

They seem correct!

I have to say I am going to have ht better answer of all!!  The answer is, "WAY TO MUCH" to make it worth your time to mine alone.  I also checked over the answer above and I have to agree with what they have written.

Well, did I win?  Seeing as there were no other entries I must be in the running at least.  What more do I need to do to win the coins?

I made the following assumptions.
1) you want to know how much ice we could melt with the energy required to create 100 BTC
2) you would accept an average value since Bitcoin generation is probabilistic
3) we would assume the latest available technology for energy requirements
4) the ice we are melting begins at STP (standard temperature and pressure)

one block = 25 BTC
100 BTC = 4 blocks
average number of hashes to solve a block = difficulty * 2³²
average number of hashes to solve four blocks = 4 * difficulty * 2³²

Antminer S7 requires 1210 W to generate 4.86 Thashes/s OR

1210 J/s
--------
4.86X10¹² h/s

= 2.4897119341563786008230452674897 X 10^-10 Joules per hash

current Bitcoin difficulty is 178678307672

average number of hashes to solve four blocks = 4 * 178678307672 * 2³²

average number of hashes to solve four blocks = 3069669951823463579648

average energy required to create 100 BTC = 3069669951823463579648 hashes X 2.4897119341563786008230452674897 X 10^-10 Joules per hash

average energy required to create 100 BTC = 764259391297.6113027518683127572 Joules

Given Heat of Fusion of H2O => Hf = 334 J /g

q = m Hf

from the average energy required to generate 100 BTC know that q = 764259391297.6113027518683127572

rearranging the HF equation to solve for mass we get

m = q / Hf

m = 764259391297.6113027518683127572 Joules / 334 Joules/gram

m = 2288201770.3521296489576895591533 grams

m = 2288.201770352129 Tonnes

Therefore generation of 100 Bitcoins with sufficient Antminer S7(s) at current difficulty would melt approx. 2288 Tonnes of ice at 0 degrees C.

(edit)

what is 'q'? can you explain?

and the amount of energy and the temperature rate to create 100 btc is ever increasing and requiring longer time as the bitcoin block halves, i believe this kind of question or clue has almost no model answer, no idea.

I will like to start refreshing my memory on these subject. so, every week i'll asking one question in physics and chemistry.
With little gift to anyone who provide the correct answer.

Physics &
Chemistry




i remember back in back in school days
So, the question how physics and chemistry do we have on bitcoins talk forum?


Heat of Fusion of H2O => Hf = 334 J /g

=> q= m Hf


If, the above equation is true
=>Then,what is the amount of energy will be required to create 100 btc and at what temperature?

All answer's must be express in equation

Thanks
