However, the line "invest in Bitcoin and cryptocurrencies" is just like the tiny tip of something enormous. It entails knowledge; it entails careful research not just of Bitcoin itself but also of how to securely access and keep it.
Tbh I think if their friend sent them this and their førend isn't into crypto but they are then it's perfectly fine. Probably just something they found online while they were browsing...
I assume if his friend wants to get into crypto, he'd try to get some advice from Op at least...
But also the slogan is kinda true, everything else funds the banks and the fat cats that exist only to exploit the system while bitcoin and crypto is a separate endeavour so far at least.
