I´d be careful with IOTA.
Look at the recently discovered issues with IOTA that even made it into mainstream media outlets like Forbes:

I tend to be bearish on the Internet-of-things buzzword in general and IOTA´s value proposition is basically based on
this area of technological progress. If you add the recently discovered vulnerabilities and the huge supply I don´t really
see IOTA as a particularly good investment.
