My Tokpie Exchange journey, i deposited my fund to trade their. I bought the native token of the exchange (TKP) but i can't trade it back to Eth, BNB, USDC or WBTC.
I wrote to support and they told me that i should place order based on their terms or forget about it. But the evil part of it is that they are selling below the price they want us to place.
This is the first time i am hearing about this exchange but i am not sure i understand your situation. You said you purchased their exchange token but you are not able to trade them, but in the next sentence you said that the support team asked that you should place an order

, which means you could trade the token.
Edit:
I checked their token in CMC and it looks like a dead token with zero volume. There are plenty of decent exchanges in this space and still users are chasing new ones and are willing to take risk which is unfortunate.
