I spend all my extra income investing in cryptocurrency. But I don't make a lot of money at my job like you guys, I'm a cancer researcher, not a programmer. I live very simply, drive an old (1996) used car I like, and don't buy a lot of extravagances. I need cryptocurrency to succeed so I can retire someday or be able to afford having a family. My crypto portfolio is currently worth more than I make in a year and has given me great hope for the future. That hope and potential freedom has outweighed any of the stupid things I used to spend my money on.
