Be that as it may, everyone is entitled to spend their money as they see fit, no? If the person purchasing understands the risks involved (at a minimum a 100% loss of funds) and is willing to assume that risk, why not?

When I purchase anything that is ONLY good for crypto mining, e.g.: a Bitmain L3+ or a Bitmain S7-LN, etc., I have assumed the risk that it becomes 100% worthless. I also ONLY spend what I am able to lose without impacting my ability to pay my regular bills, like mortgage/rent, electricity, internet access, etc.

If you can't afford to play the game today, watch from the sidelines and learn. When you can afford to play the game, start slowly, don't risk homelessness, don't rely on the coin you've chosen to moon as the odds of that happening to a small fish are incredibly long.
