The guy said on telegram that he will continue to aidrop a lot more tokens. And that dump in the graph happended because the guy said he would sell some tokens to make developing a full time job.
If he was trying to scam anyone, i dont think he would annouce before selling or would airdop almost all the tokens.
I dont now if the technology is good or not, from my limited knowledge all seems fine.
just my 2 cents
