A lot of users are in that situation,where they either forgot the password or the wallet seed or simply do not know where you have taken the back up of the wallet and in my opinion around a million bitcoin are lost forever and the majority of the coins are from the beginnning as it was easy to mine the coins.It is not possible to get those coins and no one can help you in recovering those.
Yep think there are quite a few of us who have lost Bitcoins and Litecoins from the early days lol. There was one guy over here who even went as far as searching the rubbish dumb for a hardrive which he threw out. If he could have found it he would have also been a millionare today.
