Did you use mycelium on a mobile, then stop using mobile and go to desktop exclusively so you could use Core?

I agree with dooglus; however, I use them differently than him.

I use core on a laptop/computer.
I use mycelium on a cell phone.  I use the phone as a mobile hot wallet.  Example buying coffee and presents.
I use the computer for control over my coins so that I can specifically decide on my payment/crosss payment/change address/ and the fee I want to pay.  So, handle multiple payments in the same transaction which is good to make it just a little more anonymous.

Let's say I had an address of coins I won from a gambling site.  So, insead of using that and the change gets mixed up with my other coins, I can use core cointrol to still make the same payment, but have the change to back to the same address so they are not mixed with other funds.

The only way to do this with mycelium (currently) is to use pycoin or even import the seed into another wallet app which does have cointrol (import not move).

dooglus,

I was referring more towards using the same wallet.  So, instead of making a bitcoin core wallet and importing the addresses (or moving the coins), I wanted the ability to keep mycelium and continue to use the master seed along with all the prior addresses unlinked (so to speak).  You can import the account(s) into Electrum giving you access to all the addresses AND also have coin control.  This does NOT mean that I don't use core.

So, core at home/server/semi cold storage.
Mycelium for mobile use with the ability to also use on electrum for specific reasons.

To me, it's a step easier to have a master seed stored in a safe than a USB key with a wallet.dat on it.

Do those ads possess any danger to the mycelium users? Because i feel like they can.

Android itself isn't safe anyways. Googleplay is swarmed by all kinds of filth there is. I wouldn't carry my wealth in an android device. Never.

One day you'll download a game which asks for a stupid permission aaaaand its gone.

I've read that large amounts of that sum have been eaten by unexpected legal costs. That could of course be a fudge, but I looked at it when it was proposed and well and truly couldn't figure out what was in it for me. Rather sad that an operation with so much good will ballsed it up.

I haven't upgraded to this ad version, but if something is forced or I wipe the phone and have to download the new version what other mobile wallets can I directly import the Mycelium seed into?

Copay doesn't seem to have anywhere near the same functionality I'm used to. Anything else?

Currently, it crashes if I try to add a new wallet... From what I can gather, it is a "SegFault" of some description, but because it is running "native" code via kivy, I can't see the exact cause of the problem... the error message is a bit obscure

Previously, I had it go into some crash loop where it would just instacrash on app startup... the only way around that was to clear the app data/cache, and then restore my wallet...

I guess that means the ads weren't airtight contracted then...

it looks like there might be a less obtrusive sponsored section.

i'd still prefer to pay them something.
