You can't just invest in a coin because the devs are known. Besides, people will just start faking IDs or their identities to gain trust then scam at a later date so being known really isn't going to stop scams. Personally I'd avoid all coins unless you actually believe in them for whatever reason.
Buying a coin solely on the basis of it having an ID'd developer is just as foolish as buying a coin because it has a pretty logo. A developer who refuses to identify himself, however, is a red flag. If a coin accumulates enough red flags it's best to avoid investing in it. Crypto is like poker. The key to winning isn't usually winning more. The key to winning is to contain your losses.
