But the creator of Ethereum is not...
This may or may not be a scam per se but it looks like yet another shitcoin that will aimlessly wander the valley of altcoins, serving no real purpose other than providing a cashgrab for its devs.
In this day and age only creators of actually innovative blockchain tech are worthy of remaining anonymous. Copying somebody else's idea and tweaking it a bit is not a good enough reason to remain anonymous. If it is for you, you have to question your skills as an investor.
The last decent coin idea with an anonymous creator (he didn't even really create it so much as come up with the idea for it) was Grin. It was actually developed by Andrew Polestra, so this isn't even really a good example.
If you're reproducing old ideas, remaining anonymous is suspicious because it looks like you're just trying to make a quick buck without any negative blowback.
