Normal people would hire or call a computer specialist to set it up and whenever a problem arises, you need to call him, which will cause extra costs.
Mining is involved directly in Computer Technology and requires special technical knowledge most common people don't have, if not studied.
If that's what your expertise in dealing with gadgets and stuff then I won't recommend going anywhere near mining, in 2024 you need a huge capital to buy ASICs and set it up which is one time investment but for sure it requires regular maintenance and if you are going to hire someone every time that's gonna cost you a lot.
Holding and mining are totally different, and I wouldn't compare one with another but the point you are trying to say is right just buy bitcoin and hold them for years which is more profitable than investing on mining hardware.
