Ignorant to do this verification before sending funds from your self-custodial wallets to the exchange wallets will always cost you excess expenses on transaction fees from an exchange to another before you could realize yourself and call it mistakes.
To avoid this cost you fit use blockchain wey get zero fee/low cost as no be every time you go dey use Bitcoin for transferring (when you dey wan sell). Make I say you deposit for Binance exchange without knowing say dey dun delist Naira P2P and you been wan trade dollars to Naira. If you wan send that money to another exchange for trading, you can use other Blockchain to move your coins with less transactions fees but no forget to convert am back immediately you receive the money for the other exchange because altcoins dey extremely volatile and if you go hodl the money for the altcoin, you fit lose some wey go pain you. Person no supposed dey lose money anyhow this period.
For this industrial, everything wey you dey do supposed dey dey double checked before you proceed. Make am a habit because this industry no too get second chance make you no go dey think say you still dey were you fit call customer care to help you as you dey do for Naira transaction. Some platform get customer care sha wey fit help you but to reverse your confirmed transactions, that one dey always impossible.
That's a very good alternative if a users falls on such category to had sent or received funds from a disabled naira from an exchange p2p like that. So save cost of forwarding the fund to other exchange, it's necessary to consider using a no fee blockchain to transfer the funds to other suitable exchanges and always make sure you checkmate on the next exchange before proceeding.
It's quite alarming that some beginners would think crypto blockchains is as the fiats system where mistaken transactions can be revised after the fund sender has layed complains to the authority.
Let's not be so carless like that here on crypto blockchain and avoiding this is to always cross check what ever transactions we might be up to before proceeding to finish the transaction because even if a customer care may attend to you, it'd be unlike the fiats system.
