Should I Build a Bitcoin Mining Rig or Buy Mining Stocks?

I get that this is a mining topic and not really about investing, but my question ties into mining and I bet there are some experts around here. So, between building a mining rig to mine Bitcoin and putting money into Bitcoin mining stocks, which way is smarter, assuming cash isn’t an issue?

In my country, company shares can be bought through a mobile phone, which anyone can do. Just money is not enough for mining. If your electricity is expensive, then mining is not profitable. The minimum batch for investment is a minimum container for 100 ASICs to quickly start mining, but you need to understand this and have at least 350 kilowatts per hour of available power.
