I looked at decentralized exchanges, and the liquidity there is very low.

You need to select any exchange from the list and send tokens to your Solana exchange wallet. First, send the minimum amount to verify receipt. You will see this information on the exchange.
If the tokens @OP holds are genuine, there's no need to go to DEX with low liquidity, there are still plenty of CEXs that support $FIDA. Well, @OmegaStarScream has already provided the reference.
I can't get you clearly clearly, you purchase bonfida on a centralized exchange and sent to Trust wallet. What you have to do in your trust wallet is to enable bonfida to reflect on your trust wallet. Since you said they are built on BNB network, you can possibly copy the contract address from coingecko, ticker and others to enable you see your bonfida on trust wallet.
He didn't even say he bought it from CEX, most likely, he got a fake token from a scammer's address.
I am not sure if Fida has expanded its usage to other networks, but as far as I know, Bofida was launched solely on the Solana network and serves as core infrastructure for the Solana ecosystem. Without needing to know the source of your funds, I am 99% certain that the Fida tokens you hold are a scam. The value of unofficial tokens will not be reflected in any wallet.
You're right, Bonfida (FIDA) has never been on any network other than the Solana blockchain. So, we can confirm that the token held by @OP is a scam token, likely intended to poison his wallet/address.
