There are many projects like these especially new one. Not every one is familiar with github, an open source code for their notes. Actually it is quite easy to use, if all crypto enthusiast knows how to use it then many projects can be easily flagged as scam and could be a basis of their progress. You could actually compared which is the one really working on the project and the one who is only focus on trading.
If the project isn't developers aren't familiar with version control concepts and systems like git and github then they aren't competent enough. Such projects really need refined senior developers in their team. So that's not an excuse no to show progress and early platform releases prior to the main, stable platform release. Crowdfunding shouldn't be difficult than it is today. If you can't take your promises, don't make one. I frown at projects that collect funds and then do nothing.
