the suggested tip strategy may not be optimal => \exists some chance that a malicious strategy is optimal
how can the Proof of Work be easy enough that IoT devices will have the ability to do it for their own transactions but still be hard enough to prevent 33% attacks or Denial of Service attacks on the system
Proving (1) seems difficult if not impossible. Equilibria in the Tangle provides some relevant analysis.
(2) might be addressed by coordicide and never occurred in Iota because of the use of a central coordinator
legitimate use cases
I agree; iota may be "put to better use as a permissioned second-layer micro-transaction solution amongst a number of semi-trusted devices on top of blockchains"
