I think iotex can have the late comer advantage in terms of solving privacy centric and scalability. Its more advanced than iota. Still my verdict to their aggressive schedule to release testnet in April is way too challenging and it will most likely fail. giving the fact that they are still hiring for talent for the commitment of phd. its hard to see that he can hire people quickly for this kind of project. another issue is the resource allocations. he has no clear picture of how to operate his company resource in terms of research and other activities. seems everything is up on the air by talk. its highly speculative at this point. let wait to see the wave coming in the announcement of the testnet.
