Say you buy $10k of any crypto currency and you pay in cash / real money
Since that amount has to go somewhere (less costs)
where does your $$$ money go or to whom, it has to benefit someone.
Don't equate it to buying stocks as those makes you part owner in an asset.
Please don’t start telling me about the technology behind cryptocurrencies.
It goes to the person at the top of the pyramid, to pay for electricity and mining rigs.
