Good evening everyone. I've been out of the cryptocurrency scene for a couple of years and I've stumbled into a minor issue. I've been trying to figure out if it will be viable to move some Bitcoin from one wallet I own to another without a fee. Specifically, I'm trying to send 0.2BTC from an Armory wallet to an Electrum wallet (latest stable versions of each client). The 0.2 BTC is all I have in that Armory wallet at the moment and I'd ideally like to get it to Electrum intact if possible and thus without fee.
When I try to send at 0 fees with Armory, it warns me I need 0.00012407 "for the size and priority" of the transaction. I am not sure how it calculated this or if it is a baseline estimate (which is pretty close to the default 0.0001 fee.), but it will allow me to send at 0 against its advice.
Reading over the description of how transaction fees are calculated my transaction seems to miss some of the "gotchas" that the protocol requires a fee (ie 0.2 BTC is not small enough to require fees), the coin itself is definitely old enough as the transaction that granted it to me was from 2014 and I haven't moved it from Armory since then etc.. but when I read over a variety of articles and posts there is a lot of variety in the confidence that such a transaction would be actually be validated sans-fees. Some older posts from 2013/2014 don't seem to be of use any longer, as it seems that transactions were more likely to be processed without a fee back then compared to now. Others suggest that at the value I still shouldn't have much trouble or to just give it a try and see
So given the current state of Bitcoin in 2016, should I attempt to send the 0.2 BTC to myself without any fees and have a reasonable expectation of timely (within a few days ) processing? Should I send without fees and my transaction goes unconfirmed for days, what would be the best way to "cancel" it and try again? Is there another way around the problem that I've not yet considered?
Thank you in advance
