It will depend entirely on your budget and noise tolerance.
You have three options:
1) Mining with electric power and mining equipment newer than the Antminer S9.
2) Mining with renewable energy (such as solar panels) and older miners (S9, for example).
3) Mining with renewable energy and modern miners.
1) Let's assume you have a huge budget and buy an Antminer S21 XP Hyd (to avoid air conditioning costs for cooling), with a power output of 473Th/s, a consumption of 5676W, and a cost of approximately $16,000 including shipping and taxes. Assuming you live in the US and the cost of electricity is $0.15/kWh, your daily profit would be $2.79. An ROI of at least 3 million years.
2) With an Antminer S9, which costs around $200 on the current market. 14Th/s, 1300 watts, and a hell of a lot of noise. Add to that the fact that you won't find it new, so you'll have to buy it secondhand (average lifespan: 2 years). As for the solar panels, they'd cost around $1,600. $0.69 of profit per day, a tenth of a human's average lifespan just to recover (7 years).
3) Same example as 1, but add $6,700 for the solar panels and all that. You'd get a daily profit of $23.24. $16,000 + $6,700 = $22,700, giving you a total of 976 days to recover your investment (a little over 2.5 years, the rest as profit).
Currently, it's difficult and expensive to mine Bitcoin. If you still want to mine, here are some tips:
- You can store everything you mine until the price goes up and then sell it. That helps.
- Perform maintenance on the miners once a month if you live in a dusty area, or every three months if you live in a clean environment (needless to say, with the mining equipment turned off).
- Always have a fire extinguisher on hand and don't place cardboard under the miners (I speak from experience).
- Don't even think about solo mining; always look for a pool.
- Always look for mining pools with merged mining, so you can get some extra.
- Try to mine in an isolated location, as the noise from the miners is very loud and can disturb neighbors (even those 5 houses away).
If, despite all this, you're still interested in mining, I can only wish you luck.
