Quite disingenuous for him for him to say that Bitcoin lacks improvement and that improvements should be applied sooner(which going the slow route totally justified, because you know, $700b marketcap, hence we really can't afford to screw this up); knowing that Cardano itself is known for taking the slow heavy-researched route in terms of development to make sure that the updates have no bugs and such.
Exactly, his ADA has taken a slow step on improving it's performance, so it doesn't make sense for Charles to say that bitcoin lacks improvement because as a dev, he should know that it is not easy to make iterations especially as bitcoin is a prime mover in space.
How old is Cardano compared to Bitcoin? Maybe that's where he's coming from?
Okay, but how can his opinion affect the crypto industry?
It probably won't if you're talking about cryptocurrency as a whole. It's just that Bitcoin neutrals or doubters would buy ADA if they find out what he said.
