If you invest money you can't afford to lose then that's bad lol. Play it safe always the genius idea! Thankfully there is so much more opportunity these days to bank. So many 100s of various ways you can bank by using the Internet. Which is very awesome for people that are willing to work hard! 

Clearly the oil era was more risky since it required you to invest more physical energy. These days you can generate value in the comfort of your own home. Clearly also these boys early in the Crypto industry will become extremely rich. And perhaps can even leverage that into AI research to bank some more! 

Especially since we are more people on earth and we are starting to make all global there truly is more cash in this industry! And it's also open for more people all you need is an Internet connection and you are ready to go!
