No, but can you prove the opposite?


It never is the burden of proof in an argument for someone to prove something didn't happen. Please try harder.

After all, I am on your side. But using such a retort just won't fly, logically.
Also, I would hope the dev possesses at least some of his coins. Otherwise, there is little motivation at all for the dev after the ICO ends to continue support of their coin. (Even if the motivation is to pump and dump on everybody.)
Forgot that people can't detect sarcasm online that easy.
This remains a scam. Good luck.
