Yes, I think bitcoin mining is a profitable business these days but you should know that bad days will also come when there will be no profit and even loss especially during bearish market but at the moment as market is growing miners are making good money but we all know this business is not that profitable like it used to be in the past.
Given the current value of the cryptocurrency, mining is now very profitable. And this applies not only to bitkin, but also to the rest of the cryptocurrency. After ethereum reached the price of $1000, I took out my outdated hardware that I used in 2017-2018 with cards 1066 and resumed mining ETH.
