Cryptocurrency companies that can buy shares in?

[samtheman]

Ok so after browsing these forums for a bit i dont feel comfortable buying bitcoins right now ( i dont know enough about computers/how to set up a safe security etc) because it seems like a lot of people are getting coins stolen even when using the recommended security. Was thinking of buying shares in a new company to do with cryptocurrency, does anyone know any? On ASX (Australian stock exchange) nothing comes up when you type in 'cryptocurrency'...
