Thanks a lot guys for all your help and to direct me into the right direction for importing my old wallet.
And thanks for the warning not to sent my stuff to others.
May you all live in interesting times :-)

PS I looked for a thanks-button to show appreciation, but havent seen one.

Hi guys,

i hope you can give me a short advise. Many years ago i have done some mining and i saved my wallet.dat from official bitcoin client at this time.
Now there was some forks and splits etc. and i want to make sure i mess nothing up.

Some years after i mined bitcoin, i just could download the official wallet, install it, copy my wallet in and it was imported.

Is this still the case if i donload the official wallet ? And what is the official wallet ? Here i see only IOS/Android: https://www.bitcoin.com/wallet/

Questions over questions, i hope somebody knows.

thanks in advance
Davisss
