Firstly, speed bumps, setbacks and controversies are to be expected in technological innovation. With that being said, It's important to note that in as much as Richard Heart may be correct about the shortcomings he pointed out ( like a sociopath) about IOTA, there's still a lot of room for improvement considering that the crypto ecosystem is still in its infancy. Richard Heart's perspective, on the other hand, is that IOTA is just a terrible crypto project that has zero prospects. That's a really biased view in my opinion. IOTA has a brilliant and achievable concept as long as the team sticks to their plan on the long run.
