Withdraw all

[peoplma]

I've been having trouble trying to get a balance from a label address and withdraw all of it. An error is raised saying that I don't have enough when I try to withdraw the whole balance - obviously - due to network fees. But using the block_io.get_network_fee_estimate method returns the wrong fee amount for bitcoin, so I can't subtract that from the address balance either. Is there a better way to withdraw the maximum amount from an address?

// , These sort of fractional transactions kind of get killed by calculations for fees and other things.

Fee estimation has gotten alot simpler since this issue was opened. Here's how you get the max withdrawable balance now:

1. You can just use the max available balance to get a network fee estimate.
2. Then make another call with amount_used minus estimated fee returned.
3. You should be able to request the withdrawal with the amount in (2).
