hello i was looking arround for a btc miner to make profit but i couldnt find any that make nice profit my budget is €500 does anyone have any tips or advices i can use? Or any specific models?
With €500 you can only get an altcoin miner and make profit for a while, still I don't guarantee that you will make your initial back, this reminds me of Kaspa miners from ICERIVER, I got each for $400 and I was able to make $100 back, today they are no more profitable, unplugged and gathering dust.
You can get a Canaan Avalon miner with this money, something similar to the picture below.
With Just 140 watts you can plug and forget it for years, maybe you can hit a block one day who knows? But know that this is a kinda lottery, with 6TH/s you are better than those using solo miners with 2TH.
I'm not sure that this ASIC can work for years
This company have been around for many years, so i doubt quality of this ASIC is that bad. Although if you're talking profit, it's efficiency (J/Ths) isn't very good where ROI is probably impossible.
Oh and I'd definitely play around with those online mining calculators like the asic profit ones to get a rough idea of what you'd earn. Just make sure to dig into it all before you drop any money on gear or services, don't rush in blind!
