Because there is NO regulatory body in cryptocurrency that can make that into law., Everyone can create a website, everyone can create a token and everyone can create an exchange site.
Just decide within yourself to be of GOOD and not evil.
Only then can we have transparency.
Regulations might not come that soon and even if they do, there will always be shady projects. People will still lose money because they don't understand the nature of the projects. By working together and bringing the information to the community will you have a more transparent crypto space. People would do better if they knew better.
The only party that can give you transparency is the team that has a direct relationship with the project itself. That's the main point on this case about how we can encourage trusted developer.
