The suggestion of holding on until the price goes up might be an option, but if the OP still wants to clean out his wallet, he should deposit more than $20 of BTC. $50 minimum is more than enough and it will also be reduced by a network fee of around $11 BTC.
But the current OP has never appeared to respond to much of the feedback given, whether he has solved the problem or just created a useless thread.
Just in case you missed it, OP did an update just a few posts above yours and the cashout attempt was successful.
OP's purpose is to cash out the BTC in fiat and not to withdraw the BTC.
As for added information, the minimum amount to cash out in Binance P2P varies per payment method
(per country) and depends on the buyer's minimum set amount. In our case, here in our country, that $20 worth of BTC can be converted to our fiat currency thru Binance P2P as long as there's a buyer that accepts a minimum amount of that range.
Since the concern is now solved, OP can now consider locking this thread.
