hey everyone, I've been searching for a good BTC miner to earn some profit, but I haven't stumbled upon any that are actually profitable. I've got a budget of about €500. Does anyone have any advice or recommendations for specific models?
I think for that amount you can buy 2nd hand unit like s19 units but I do not know if its profitable in your current place.
Why not share with us first your current electricity rate? For s19 units if you have a $0.03 electricity rate, then it's profitable except above $0.05.
You can use some tools like https://www.asicminervalue.com/ to find what unit model is profitable in your country.
Once you find the model unit you like, ask @offordscott if they do have a second-hand unit that fits your budget.

Since you intent to make profit, be careful with small/solo mining device. While some of them have have good efficiency in terms of J/TH, ratio of it's hashrate and price usually isn't good compared with bulky ASIC. And if you're willing to reveal country or region where you live, other members may be able to give specific seller recommendation.
Before you buy an asic you should use the calculator

Modern models of asics cost a lot more, and older models can mine at a loss.
What is your cost of electricity?
Do you have the ability to install a noisy asic in your facility?
If you answer these questions, the communication will be more useful.
500 makes a profitable BTC miner tough, electricity costs bite! Older S9s are good for learning, not profits. Try altcoin mining and swapping?? Cheap power helps.
And also keep in mind profitable today with BTC @ $87500 does not mean profitable tomorrow if it drops to $75000. The same thing applies if BTC goes up, you might not be able to make a profit today, but if BTC kits $120000 then you might be well into profit.
Same with power. If you jump from $0.04 kw to $0.05 (yes it's a 25% jump) that could kill profits too.
Even minor fluctuations in cost could hit hard. Add on any other costs such as more cooling needed for the location where you have the miner.

If I tell you that there is one that makess profit it is a lie.
There is no plug and play BTC miner that is profitable, they do exists but solely for those who want to try their lucks with BTC solo mining, which may never bring you anything for years.
These type of miners have to solve a block on their own and that's a long of work, it is like trying to hit a target with 0.00009% chances of winning, few people have became lucky with this in the past but believe me, they are like 2 out of 2000 people like them trying their lucks everyday.
For such miners to be cheaper, they power consumption has to be lower and this makes the hashing power to also be lower too, so this machines are not good for someone who wants to make income every day or even monthly, it might never happen.
With a 500 budget, it's tough to find a bitcoin miner that generates good profits. You might consider a used miner or look into mining altcoins which can be more affordable. Joining a mining pool can also help you earn consistent rewards. Be sure to check electricity costs as they impact profitability.
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.
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.
