lowest BTC price analysis by miner technologyWe discussed about miners and mining viewpoint for preparing a BTC in previous posts:
A) BTC Analysis based on Block frame and halving
b) BTC network analyses from miners viewpoint
We predicted to see new asic miner technology and hear about new miners.
2 month ago, Bitmain introduced new asic miner with 7 nm technology which they called S 15
ASICminer is another company who claim their new miner machine can worked with 80 TH and 4200w power usage also; they used 8 nm chip in their miner machines.
Last well known miner machine antminer s9 prepare 14 TH by using 1370 w
I used my new Power Usage Index instead power efficiency, which derived by dividing device power usage to hash power.
PUI:
1- S9 = 97.85 W/Th (16 nm chip )
2- ASICminer pro 8 nano = 52.5 W/Th ( according to the ASICminer website 8 nm FINFET technology )
3- S15 = 57W/Th ( according to the bitmain website with 7nm FINFET technology )
We can assumed new technology reduce power 50% per Terahash.
In bullish market, fresh and updated miners who are, using new technology wants to overtaking traditional miner by sold their new BTC with lower price than S9 PUI .
Today BTC network hasharate is about 33.55 EH and if we assumed electricity cost 0.1189 $/w AVG. BTC block rewards 12.64 BTC per blocks
With all of above information and last 2 posts we can estimate how much BTC miner machines paid for electricity to generate a BTC
We can find BTC price roughly near 6200$ and 3300 $ for both 7nm and 16 nm chips PUI (16 nm 97.85 W/Th and 7 nm 52.5 W/Th )
if all of the above parameters stay constant we can predict 3300$ for lowest BTC price at the moment ( :D )
Powercost
lowest bitcoin price based on fundamental accoding to the whattomine (simple website to etimate bitcoin mining profit) :
we need to have 35000 Antminer S9 with 14 TH specification to build a Bitoin during an hours,
if each Antminer used 1.372 kW per hour this system need 48 MW power !!!
a- If you are able to prepare this power source you have to paid 48000 KW * power cost KWh
b- we assumed typical power cost 0.1 $ we should pay 4800 $ for preparing a bitcoin
c- if you are able to build this mining farm you have 35000*14 TH = 0.49 EH on bitcoin network
proof to above statements from another view:
==============================
today Bitcoin network have 42 EH (variable upon to miners but when last time difficulty adjusted network speed was 37.04 EH ) mining network speed and bitcoin network adjust himself by difficulty according to his rules to make a block during 10 minutes.
note that every block generate 12.66 BTC rewards for solver.
during an hours typically we need 6 blocks so we have 12.66*6= 75.96 BTC.
75.96 BTC generated when u used total network speed ( 37.04 EH) so for 1 BTC we need roughly 0.49 EH
Above information drive me to this thought bitcoin can not maintain below 4800 $ more than an hours.
==============================
Residential rates in the U.S. range from 8.37¢/kWh to 37.34¢/kWh.
The average (residential) national electricity rate rate is 11.88¢/kWh.
From (a) we can estimate lowest bitcoin price 48000 KWh * 0.1188 $/KWh =5702 $
