Bill Gates said he doesn't own any cryptocurrency because it isn't 'adding to society'

Bill Gates said he doesn't invest in cryptocurrency because he likes investing in things with "valuable output."
Gates has cautioned people against investing in crypto before, especially those with "less money" than Elon Musk.
Gates has also warned about the environmental impact of crypto.
"I don't own any," Gates wrote. "I like investing in things that have valuable output. The value of companies is based on how they make great products. The value of crypto is just what some other person decides someone else will pay for it so not adding to society like other investments."
