I would like your experience:
How BTC will one stand alone Antminer mine? Over its lifetime
What does it depend on?
I am aware that it depends on the model etc. - I would just like to have an idea of the magnitude we are takling about... is it one BTC or 10 BTC or more?
What is a realistic expection?
Thanks for your input
Hey Neun,
Depends on mining difficulty and your hashrate (and maybe luck, although I think most mining pools offer a payout method which pays users daily regardless of how often the pool finds a block).
Difficulty is calculated and adjusted (up or sometimes down) every 2016 blocks (approximately every two weeks).
Bitcoin historical difficulty is available on this chart: https://bitinfocharts.com/comparison/bitcoin-difficulty.html
A single Antminer's hashrate (depending on the model) is measured in TH/s (e.g., Antminer s9 around 14 TH/s, Antminer s17 around 50 TH/s I think).
1 KH/s is 1,000 hashes per second.
1 MH/s is 1,000,000 hashes per second.
1 GH/s is 1,000,000,000 hashes per second.
1 TH/s is 1,000,000,000,000 hashes per second.
1 PH/s is 1,000,000,000,000,000 hashes per second.
1 EH/s is 1,000,000,000,000,000,000 hashes per second.
1 ZH/s is 1,000,000,000,000,000,000,000 hashes per second.
1 YH/s is 1,000,000,000,000,000,000,000,000 hashes per second.
Factor in the mining pool (you will need to use a pool unless you have a huge amount of hashrate) and their payout methods (e.g., PPS, PPLNS).
For example, PPS pays you for your shares each day regardless of whether or not the pool finds a block.
PPLNS pays you after the pool finds a block (could be multiple times a day or could be days in between, depends on luck), the block reward is divided, accordingly, among everyone mining PPLNS on the pool.
If you're looking at profits in terms of fiat (e.g., dollars or euros), you can factor in the cost of your electricity (and how much your mining machine(s) uses) vs the market price of the amount of bitcoins you've mined.
At the moment I think an Antminer s9 (or s9j or s9i) can earned about 0.00010 Bitcoin or less per day. A little less than a dollar ($1).
The machine could also stop working, break or parts of it burn up. I think you can buy used machines for sometimes less than $100 or a little more than $100 (e.g., $150) if you check around online.
