Hello, i did what you said, copied the private address and tried importing it into Electrum client, but an error always comes up "the following inputs could not be imported:"

edit: Nvm it worked after i shut down the bitcoin core client. Thanks a ton guys, what a helpful community.

Hello, i recently purchased 1 BTC and deposited it into a BTC core wallet that i had recently downloaded, and then finding out that i now have to download 50 gigabytes of data in order to access the BTC.

I'd rather not wait for days - is there anything i can do to speed things up? I knew about the 21gb torrent with the bootstrap.dat file but i'm already at about 15gb now so it's not worth it.
Any suggestions would be appreciated.
