Laptop crashed blockchain lost

I've sent all my bitcoin to my new electrum wallet    Do i need to leave the old wallet running until the transaction is confirmed ? or can I close it  or even uninstall it now if i dont need it ?

No, but you certainly want to save the wallet. You never know, someone might send coin's to your old address. If you loose that wallet you've lost those coins.

I think Electrum is deterministic right? So you can't import other keys into it?

You can import other keys into it with the caveat that those imported keys are not recoverable from seed like the other addresses are.

Got it, thanks for the correction.   So, does it have a sweep function for paper wallets? I haven't checked it out. I've been very happy with the blockchain.info wallet. I've never once d/l'ed the bitcoin blockchain.

The best is to update the blockchain.

well its not a proble mwhen you created you wallet or while using your wallet the blockchain automatically make backup of the wallet and send to the email address.. please go and see if any backup sent to you wallet if so you are secured othrewise you get out of your bitcoins ...

I m feeling so sorry for that..

I'd like to add that it would be nice to the bitcoin network if you carried on running bitcoin with the blockchain.

You can still use electrum for your transactions but only bitcoin core will actively work as a node and help out with network traffic.

If you have a decent PC and don't mind the extra overheads of running a node (bandwidth usage, CPU & RAM usage) then you'd be doing your bit to support bitcoin.

I would recommend that you use a client that doesn't need blockchain. Much easier and no disadvantage.

Actually the disadvantage is that you need to trust other computers to be honest about the blockchain, while f you run a copy of the blockchain yourself you are less at risk.

Having the blockchain makes you a node as well, which make the network more secure.
