Re: Bitcoin OMG! including Coin Control, Disable Wallet, Performance++
Thanks for this OMG client with Coin Control.
But I wonder how much can I rely on the tx size/fee estimation in Coin Control?
I just noticed that tx size estimated is 300 bytes less than actual tx size in some cases.
Maybe that's a minor bug?
The underestimation in tx size occurs when multisignature address is involved.
This tx

contains 5 inputs and 2 outputs.
The address starting with 33 is a 3-of-3 multisignature address.
The actual size is 1264 bytes, but in Coin Control it is reported as 946 bytes.
Coin Control does not check the address type, I guess.
Multisig address is larger than normal address, and ignoring address type leads to this underestimation in tx size.
Hope this could be fixed soon, and we can expect a reliable fee estimation.

You probably shouldn't be using coin control until you understand what you are doing. You have to decide what the fee is, coin control allows you to easily create a custom transaction so it is just going to take the leftover coins and send them as a fee. Be very careful! Try this on the testnet before using it on your real bitcoins.
Thanks for suggestions. I understand the risk using coin control. I will double check when using it.
So, for fees, I still need to estimate the fee myself even when using coin control?
