I am trying to change wallets from GreenAddress to Trezor. I have updated the miner with the new BTC address and am now ready to transfer my BTC funds from GreenAddress to Trezor. When I started the process I was shocked to see a .01675051 Transaction Fee to transfer only .10899048 BTC.

I found this thread on the subject https://bitcointalk.org/index.php?topic=1476536.0;all which basically says auto calculated fees are a joke on GreenAddress and to chose my own fees.  I found that fees are based on transaction size but I am unsure how to find the size of the transaction.

So now is where I need smarter peoples help.

I am in no hurry, however I would like the transfer to be completed before the upcoming fork, so I am cool with a slowerish confirmation time. If I choose 0 for the fee on GreenAddress it gives a warning stating the fee rate is too low and the minimum rate was used of .00001 BTC which makes my total fee .000084360 BTC

Is this a good fee size? Will a fee of this size get my transaction processed? If so what would be an expected turn around time for confirmations?

As my status says I am a newbie so please go easy on me with replies.
