I am considering getting into mining, and after seeing the prices of Antminer ASICs and the low stock on their website, it doesn't seem very appealing to me. Given this, and after reading a bit here, I see that people also mine using Avalon miners, which are much more affordable, although they are twice as inefficient in terms of watts per TeraHash. My question is whether it is feasible and a logical step to start by buying some of these Avalon miners, generating money to reinvest, and eventually switching to Antminers, which are much more efficient.
I had also thought about using solar panels and batteries to avoid worrying about electricity costs, even though this would require a much larger initial investment. However, where I live, most days have very good solar radiation and few clouds. Am I on the right track with this approach? The idea is to gradually save in BTC and, once the numbers work out, make the investment.
Short answer:
Avalon or whatsminers if you are in Dubai or places with extreme heat.
Otherwise you can stick with Antminers.
Beware of fake sellers there are many.
The electricity cost is crucial. The best one is 0 cents per KW. And you can get it if you use electricity for heating or if you have it prepaid. For one miner it is possible to hide it.
You can buy ASIC noise reduction box for noise reduction to keep it hidden here: https://minerboxes.com/.
Choose ASIC according to profitability try here: https://www.asicprofit.com/ -- they have the most valid calculators even for KASPA after KRC20 working correctly.
If you have expensive electricity simply go and find hosting. There are many option I recommed oneminers - https://oneminers.com/
For solar panels it is feasible but remember if you are in Europe than what will you do during winter when electricity is super expensive? Even big battery won't help. But certainly if there are incentives to build solar system with batteries, take THEM. They will pay off 2 times faster with mining.
Or you can HOLD simply bitcoin. It works as well
