IOTA can be a great coin if and only if it works.
As I remember, the algorithm IOTA is using called Tangle had many problems including security issue found by MIT researchers which was fixed.
But people complain about the wallet does not work properly and the consensus core was not decentralized.
Tangle would be outdated if Hashgraph comes up with public working core free of charge without patent licenses.
Keep watching the developments in DAG cores, and there are a few which are working on new cores.
IOTA's value will lies on failures of other competing DAG consensus technologies.
