that company bittech is a fraud
try finding an avalon a921
Thanks for the warning. I near order made an order.
I try to get a A921 but minimum sales in asia are 20 pcs.
I know you said a hobby, but how enjoyable your hobby is might depend on being able to pull even a small profit out.
That's where it depends on your cost of electricity mostly, and your space secondly - I say this because I'm guessing that you already know these machines are loud and hot.
You can start here for for a quick
checklist to get started.
If you have cheap power, go for the 841 because as it's no longer the nexgen miner it can be bought for a good price right now. If power isn't cheap and ROI/Profit is on your mind I'd say get everything in place and see what the 941 looks like. I think it will outperform the 921, in a similar fashion that the 8 series went.
I haven't toyed around with most of the other miners out there, but you should check out HagssFIN, signature for links to his reviews. Pretty sure he has most of the current miners in there.
Power in Phuket are 0.14 usd /kw and I have lot of time and space. Only the humidity/temperature can be a problem to consider.
Maybe better I wait for the A941 and see. Only problem the company in asia only want to sell to farming and not only one pcs.
Whatsminer M10 looks good but out of stock right now. Next batch are December and then I believe all have 7nm chip so M10 maybe already old
.
Thanks for all advice.
