I recently found the private key from a wallet from 2010 when I generated a block of 50 bitcoins. I imported that key into blockchain and the 50 coins showed up in my online wallet. However, whenever I try to send coins, I get an error message: invalid signature. I used the blockchain web interface from a PC for these transactions. What's up with this?
I'm installing bitcoin-qt and currently waiting it for it to sync. Should I try to import the private key there and see if that works?
I've read vague warnings about importing private keys, but nothing specific. Can anyone provide details on the kind of dangers should I watch for?
Thanks
Oh wow, you are rich now. 50k just like that, congrats. Now onto the most important part. Perhaps it's an error with blockchain.info rather than the private key? The only danger is having a keylogger finding your blockchain.info account password and emptying those coins. I'm installing bitcoin-qt and currently waiting it for it to sync. Should I try to import the private key there and see if that works?
