Real estate is at least a real thing. But if you want to invest your life savings in crypto by all means do so.
The real estate industry can never collapse longterm. People need to live in homes. It can only correct. Homes have been around for many, many centuries and aren't going anywhere.
Crypto only exists in digital form, has no inherent value, you can't even melt it down and sell the scraps, and it has only existed mainstream for, what, several years? It is highly, highly speculative and the riskiest investment humanly possible. It's a terrible longterm investment and Skippy is an idiot.
