My friend buyed Bitcoins in 2011 from Austrian Company, they make payment via Bank. After few months they lost his iPhone where is stored all data from company and Bitcoin account. From that time they is unable to find that company, i search for him but i can't find nothing. I see lot members here know all about Bitcoin from start. Maybe anyone know who sell Bitcoins in Austria 2011 year, and where can be that Bitcoins stored. They know email used on that company and we can recover them.
Since 2011 and noncustododial wallet did not used for it, possibly the coin is long gone. Even how the coin was bought has been forgotten not to talk of knowing the login details if the site used, some sites that were exchanges that time have been hacked and cease to exist. If she can get the statement of account and check, possibly useful information can be gotten there.
