I think no problem if take long time for development as long as in accordance with their road map and don't be change. So that investors still trust in this project and then this project posible can success
I agree with you but it looks like many others expect things to go much faster than outlined by the team from the very start. They are all very impatient without any reason. PayPie is not just some little fancy blockchain startup, they are trying to build a huge company that provides the economy with a new accounting paradigm called triple-entry accounting and all its functional implications, for example an improved credit scoring system.
I think there are also a lot of people who didn't even check their roadmap or read whitepaper. They just noticed the big hype about Paypie and invested in the belief that they can make x3, x5, whatever in just a couple of days.
