Well I don't know how to say this but the truth is that neither Bybit every other centralized exchange is scam free of the P2P vendors with their formations of sending traders incomplete funds from value of asset initiated to sell.
I would neither not recommend you to other platforms in regards to this vendors attitudes because few guys I know that encountered the same incident was not happened in the Bybit but other platforms.
I uses the same Bybit but have not encountered such as stated (incomplete payments)from the third party. Maybe because I considers their SUCCESS RATE in determining their trusts and reliability before opening a trade with them. So I urge you to do them same.

Also, confirm your payment before releasing the coins and if as such the vendor tries to trick as thou, you can file a scam case to the exchange escrow. You also have to be aware that the vendor might solicit for pardon that it was a mistake, don't also believe them. Block such user after dispute is dialogued. If you also don't find the exchange further convenience, you can consider others but do make your research first. Don't forget, such attributes of inconveniences is what is usually experienced in the regulatory platforms.
