Transfer Bitcoins From Bitcoin Core To Blockchain Wallet? I used to have Bitcoin core on another computer and kept it on C drive with 2TB hard drive. I kept the dat on a USB.

However it broke and on my new computer the C drive is a fast but small drive that doesn't have the space to download the blocks now. So after a google search i found some info to use my D drive for the downloads which i have done.

The problem is every time i load the software it seems to need to verify the blocks as if there is some error and constantly stays on 3 years and 7 weeks behind and never seems to get further. My internet speed is ok but not ultra fast also so the software wallet just seems like a nightmare to use now as the balance remains at 0 and i can't seem to do any transfers until all the blocks have updated i guess. Why the wallet can't do a quick blockchain based balance update to save people from this serious problem i have no idea.

I have about $50 in bitcoin in the Bitcoin Core wallet though and would like to transfer it to the online Blockchain wallet, is this possible?
Yes. It is possible. To transfer the bitcoins out without synchronising the blockchain, you'll have to create a signed raw transaction and broadcast it with a third-party provider (such as blockchain.info). You can lookup the input from a blockchain hosted on a third party provider.
