Hello,

Around seven-eight years ago I downloaded bitcoin core and had some transactions just to try it out. I saved the wallet.dat file and forgot about it. I recently found the file and is trying to download the blockchain once again but it goes so slow and I dont have the ability to let my computer be on 24/7 for weeks. Also it obviously slows down the computer so I cant work as fast as I am used to. In adition to this, some of the possible solutions to this is rooted in using the command line in the bitcoin core app, witch seeme to be very problematic since I have to wait everywhere from 5 minuts to an hour before the app responds to my actions. 

I have research the web for solutions, one of witch is finding my private key and importing it to a wallet such as electrum. I dont know how to do this, and I find it a little scary to trust some of the sources that explains it. The other solutions I have found seeme to revolve around the same principle, but on the other hand it also seeme a little scary for my that is not an bitcoin expert at all.

Do you guys have any experience with this? Any solutions (easy or hazzle) that could solve this problem? I would even love some tips on how to download the blockchain faster.
