How much computing power will be needed to mine 1 bitcoin per day or even half of it?
A good question was answered by William Douglas on Quora. Here it comes below.
To mine one whole bitcoin per day
Or even 1/2 of one per day….
In Bitcoin mining, there are at least 7–8 exahashes per second of computing power executing and growing continuously
That is :
7 billion – 8 billion GH/second
The s9 ant miner cost about $7,000. And gets 14 TH/s or 14,000 gh/s
If we assume bitcoin mining consumes 7 billion GH per second (it is most likely 8, 7 just makes calculates into prettier numbers)
And each antminer offers 14 thousand GH per second
Or .0002% of the mining (.000002 x 100%)
And there are 2,000 bitcoin a day:
83.33_ every hour
1.388_ every minute
.02315 every second
You would get .004 BTC a day
You would need 250 S9 antminers
For only 1 btc a day
250 x 7,000 = 1.75 million dollars
Or 875,000$ for half a bitcoin a day, based on hashing
You could still get more or less than the given amounts because it all comes down to chance with hashing.
You could also probably buy equipment that is more efficient with that type of money, the S9 antminer is just the most efficient consumer available mining hardware.
I don’t really like bitcoin all that much, this ridiculous computing is the biggest reason, you could power cities across the world with this energy…. And it’s used for bitcoin instead, the least efficient of all the cryptocurrencies in terms of scalability and transaction speed….
I hope I helped!
