Are bitcoin mining still actual?

So the saying "during a gold rush, sell shovels" is a metaphor that suggests that when you recognize a gold rush is happening, don't try to be the 1,000,001st person to mine for gold, because you will probably fail. So if you apply that here, manufacturers of graphic cards they earned a lot, some gold miners got rich but most of them earned peanuts.

I see a decrease in mining in my country because prices are low, bills are still high and not many of them are able to keep up.
