there have been many, many successful projects that have been in development for over 5 years. I'm speaking projects in general not just crypto, so the fact its been in development for 5 years isn't really the worse thing in the world just means they've been trying to get it right, you're also forgetting they haven't got a massive team behind them.  theyre so close to finally releasing the project i think you should wait until the project is released then comment about it taken so long in development
