It's simple.
This token created to scamming others. OP probably the creator of this token. It's dumped caused by
1. There's no demand/he failed to attract liq providers
2. He dumped it when there was a liq providers adding some money on it
The liquidity is locked but what about his pre mined tokens? He probably had an alternate address to hold his token then dump it when there is someone who got trapped by him. I assume he has sent some tokens to the his alternate address to dump it.
This is a fuckin scam token. Just caused by the liquidity is locked and it doesn't guarantee if it was safe to trade there.
There is probably his alternate address on the picture above.
Just ignore this shit scam token.
Actually these owners of the project get the confidence because of some traders that are the followers of their greed and they invest in these kind of projects. Due to their Investments they get the benefit and then the project disappears. This increases their confidence so we should avoid that.
