I consider IOTA a good hedge against blockchain based cryptocurrencies. Furthermore, the concept of a 'no fees' payment network is also very appealing. Similarly, RAIBlocks has a 'no fees' concept but seems to be much more in a BETA stage. Third, the IOTA seems well connected to manufacturers and other businesses in order to implement IOTA in real life business cases. If you have a substantial amount invested in cryptocurrencies, IOTA should be one of them.
