So I'm finally getting around to setting up multi-sig on Hansa, and I had a quick question about setting it up. Hansa has the multi-sig tutorial page, and on it it says for electrum (the wallet im using) to get my public/private keys for my wallet address. To do this, go to the addresses tab, select any address, and get the public, private keys etc etc. My question is, do I use any address under the Receiving > Used > addresses of electrum, or Change > used, or does it not matter? And it wont matter that my BTC address changes every time I make a transaction with electrum, right? Additionally, I can then use coinb.in to sign my transaction (to finalize), even though I made the initial entering-multisig transaction through electrum? Sorry for noobishness.
