First of all, I'd move this to Mining Speculation or something close to that, since you want answers from actual miners.
On bottom-left side of the page you'll find "move topic".

Second, I'm not a miner, but if it's 16 Eurocents / kWh then it may be expensive. Again, I am not sure and a miner should confirm, but you may not earn enough to cover the price of electricity and the devices you buy.
Also, I'd expect that in a couple of weeks (months?) the difficulty will "get back to normal", making it more difficult.
And, last point, with the chip shortage wordwide, I would not expect you will be able to buy new mining ASICs.
