I am using greenaddress.it and have been for awhile now and it's been good, apart from being a little slow it works well and show's accoun balance in AUD.
I have since moved to wallet 32 for a daily hot wallet just due to the speed.
I will try green bits and it may win me back.
Will the new greenbits app auto swap my old account or do i have to do a bunch of stuff?
I have passords and memoric written down if needed.
Greenbits should be faster since it's written in Java instead of Javascript. You'll need to enter your entire mnemonic the first time you use it, after that you can set a PIN if you prefer, just like the original app (or continue using the entire mnemonic each time). There's no trouble having both installed at the same time if you like.
