IOTA is the worst cryptocurrency I’ve reviewed so far. Installing the IOTA wallet was a pain. Receiving and sending IOTA tokens is technically challenging and time consuming. Address reuse can lead to loss of funds. There is no functional IOTA mobile wallet. There is no IOTA hardware wallet support.

But most importantly it is very clear that IOTA cannot be used on Internet-of-Things devices, the problem it markets itself as solving! How can a smart lightbulb or drone stay in sync with a “tangle” that requires vast amounts of CPU cores, RAM, and network bandwidth to stay in sync with?
