There are no "get rich quick" formulas anywhere. But, you can certainly get rich even with humble investments in index funds or ETFs or investing directly in stocks (after learning to invest, of course) over 20 to 30 years.
Cryptocurrencies don't have an underlying asset. They don't produce regular income like interest or dividend.
Putting good money into cryptocurrencies is not investing but simply gambling. Sooner people appreciate this better it is.
Depends where you catch it as the value rises and falls... like I managed to buy a litecoin (despite being broke asf at the time, otherwise I'd have bought a bit more) when they were only worth £2 and it's now apparently worth £51.22 each (but has been higher I think).
