If the blockchain a currency or token is on is only as strong as it's developers, then what is the best way to really find out how to trust it before investing? Especially if the developers are anonymous?
You need to have some knowledge about blockchain programming and start to dig into their GitHub repository. Anon or not are not really important if you can review the code. Even when the devs are popular, you shouldn't blindly trust them. If you have serious amount of money to be invested, maybe it's better to hire programmers to review the code for you if you cannot do it yourself.
