Send from bitcoin core without downloading blockchain I have bought some bitcoins a while back, and stored them in bitcoin core. Now I try to use them, but I have to download the whole blockchain (1 year and 23 weeks to go) which takes about forever.. 

I donwloaded the electrum wallet and want to wire the bitcoins to that wallet. 

Is this possible without downloading the entire blockchain? It would be the first time I do a transaction with bitcoins so I am a bit careful.. There is a transaction cost I can set (normal - fast) which gives a confirmation in 25 - 1 block. Is this confirmation sent after I downloaded the entire chain? 

simple question, but I do not find the answer... 

thanks in advance!
My suggestion for your case is you can use a mobile wallet and import the private key of the address which you used to receive Bitcoin and then use your Bitcoin from that mobile (lightweight wallet).

In fact, the mobile wallets will also download the blockchain and keep its database up to date with the Bitcoin database but it will not fully download the whole blockchain so it will be so much faster.
