I have deployed contract and added liquidity from PCS GUI tool. This is the contract.
0x721cF8ADA47d7F75C066f3327f80ba75befc56a4

So people was bought my token and last liquidity toal was 1300 busd and my input initial liquidity was $700+ BUSD and I was asked from Fiverr guy and he said it is okay to send my EPB tokens directly to the PCS contract address. Then liquidity may increase. I sent through metamask. sent to the address below.

But what happened when I sent the tokens to the pcs liquidity address above, poocoin chart shows looks like rugpull and token price back to the initial price and sold $920+ amount and I don’t know where it goes.
