I keep getting an error when I want to send my entire balance (not using sweep_all but transfer_split).
It says that the "needed_money + min_fee > balance_subtotal". So, I need to at least make sure I send $transfer_amount-$min_fee to avoid this error.
Given the above, how do I calculate the min_fee?
I am using "monero-integrations/monerophp" to connect to the wallet rpc.
