Yeah, that's a good point... I guess if the amount to invest replaces a dinner or a night out then it's definitely a good idea to invest just to get in, but when the markets turn down and people don't have their debt (or savings) under control, and they have to sell their volatile investments at a loss to dig themselves out, that doesn't help anyone. I'd guess they'd be unlikely to try crypto again because they've been burned.
This doesn't even include the people who try to invest their way out of debt which must be so incredibly stressful.
This is why I think it's super important for people to get their debt and savings under control before investing, because you never know what's going to happen to the economy or in your life...
