Hi there,
two years ago I exported my Bitcoin Wallet via the Windows Bitcoin Core programm into a bitcoin.dat file.
Now, I would like to access the Wallet again and sell the coins stored on it, but would have to download 150GB for downloading the blockchain in the Bitcoi-Core-programm first.
Do you guys know if there is any other way (e.g. a smaller Wallet application that can also import these .dat files or an online-service) in which I can import my wallet and transfer the coins to an exchange more easily?
Thanks in advance for your help!
There are 2 faster ways:
1) use the wallet.dat on a bitcoin core installation, but just export the private keys without syncing. Then import them into electrum (or an other SPV wallet)
2) use db_dump to dump the keys inside the wallet.dat
