I converted some BTC to my ether mist wallet early this year.
I did it before Mist was fully synced. I have a old macbook, so I still can't have it fully sync until now.
On Etherscan, I can see my Ether there. This week I decided to use myetherwallet.com to transfer my ether to my other wallet.
I have the keystore file, was asked for my password. From my memory, I didn't type in any password in Mist. My question is: Is it possible, I don't have password for my wallet? or I just forgot I did enter the password at the start? Thanks
