Been living under a rock for the past decade? ALL large miners have come from China since at least 2014. The only miners not from there as the small ones from Sidehack and the BitAxes. BTW: Bitmain is just 1 of several Chinese companies that make miners. Have you never heard of the Whatsminers, Canaan's Avalons, or the truly crappy ones from the likes of eBang?

As for reliability and repair policies - DYOFR. There are pages and pages about that here.

Are you joking? Of course, I know that all miners come from China but I wanted to know what is the experience of buying it from China. In my country, I know that some people buy it from local resellers but resellers add their commission and it makes miners less profitable. I don't have experience with mining miners directly from companies like Bitmain. How risky is it, how many miners have defects, for example, 1 out of 100, 5 out of 100?

I have heard Avalon but not Whatsminers and eBang. I haven't heard about DYOFR too, thank you for the answer.

Do not buy directly from bitmain if you are usa based buy from altairtech.io

they are legitimate.

you can do 240 volts?

the one above is good I have four of them.

I'm not US-based but I can easily receive them from the USA. That's what I was looking for, thank you very much.
I don't know if I can do 240 volts but the voltage in my country is 220 (sorry, I'm very bad at electricity, I should enlighten myself more). It would probably work in mining data centres. I can get electricity for 0.05 cents kWh.

I assume you dont mean you want to buy just one ASIC, which is fine for hobbyist mining but definitely not for profitable mining. Considering your background in altcoin mining using GPUs, this is a tougher nut to crack unless you have a decent factory of ASICs running.

So first decide what you really want to do?

Mine bitcoin for pursuing a hobby and then sell the devices to someone running the same hobby? Or
Mine bitcoin to make money?

I'd love to do both, mine Bitcoin as a hobby and turn it into money making. At the moment, I can buy 2-3 miners.
