I've always been heavily into value investing and Warren Buffett. I think I came to realize BTC was wildly undervalued and have been digging deeper and learning everything I can about it since.
I think my friend just invested in property cos everyone else was and thats fair as long as things stayed the same but they change and he stopped giving a fuck and relearning more. He also only trusts shit if its done by many many other people or is the norm.
any investment made "because everyone else is" is likely a bad investment where you've missed most of the upside
