I have think about this and i can't find an answer, how will you know that a team cares about investors without trying them out first? promises comes first from every project's team and you will have to give it a try to know the end game
The answer to this is very simple. You read comments and opinions of those who did deal with them and know something. If there's nobody like that you have to investigate yourself.
For starters you can check if their photos and credentials are real. If they're lying about their previous projects and experience or don't want to give their real names it means they're not trustworthy.
As a project member you can stay private and always care about your own privacy. It is your right and smart thing to do. But to stay anonymous as project member? Very hard and not trustworthy. Nobody who is anonymous as project member, CEO or whatever is not spending money he earned anonymously when he is at that point. At that moment being anonymous is not important anymore but how well this individual is doing in life is. At least for him.
Being anonymous or wanting to be hidden because of crypto project is wrong. But to steer your team within regulations available, helping make aware the community to raise voice and help change the regulations and still keeping your persona private is great and right thing.
2 years ago there was huge resistance in regards to exchanging crypto assets to fiat and use them with prepaid card. Till today we all made KYC for same cards, some reporting is done from financial institutions side towards regulators, no changes for regular users, loads of space for you to move privately but not anonymously. Isn't that great?
To sum it up. We all have right to be private even confidential but being anonymous or wanting to be, you don't need to be. It would mean you are hidding something or you did something wrong. But even if I am a president of USA it is my right to have my privacy when I do the '2nd thingy' in the toilet reading confidential reports.
