Yes mining is presently very profitable if you have free electricity or cheap electricity, also to get your ROI back faster you must mine every hour of every day, the most profitable coin presently is Ethereum
I agree with you if mining Ethereum is very profitable for now, but in my opinion with gas fees and the current price of Ethereum, then of course electricity costs are not a problem, because I believe we will still get profit from mining Ethereum for now, so my advice is you better mining right now before it's too late, because if you do mining right now, then you will be quick to return the capital that you spend on mining.
Before mining Ethereum, make sure we have the equipment and to buy it, of course it requires a lot of capital,
even though the equipment can be said to be expensive, the profit from mining ethereum can cover the expenses,
what is certain is that it all depends on whether or not they are involved in mining
