I was using Bitcoin Core qt
My 2 year old laptop couldn't download the blockchain, several days went by
and it was stuck at 2 hours behind...for days....2 hours behind.
So I actually bought a Sager notebook for $1,7000...very expensive, highest scoring benchmark SSD.
It's 20 times faster than my old laptop. This was mainly so I could get my bitcoins.
I moved my wallet.dat file from the bitcoin directory to an external hard drive.
Then installed bitcoin core qt on my new Sager.
It downloaded the entire blockchain in 15 minutes as I recall--extremely fast.
But now when I double-click the wallet.dat file (and bitcoin qt core program opens it),
I get this message: "Bitcoin Payment Request File Handling- payment request file cannot be read. This can be caused by an invalid payment request file."
Does anyone know what I did wrong?? And how do I open these wallet.dat files?
Thank you!
First, close the Bitcoin-Qt client.
Then you have to localize your Bitcoin folder. For Windows, it should be here:
%APPDATA%\Bitcoin
In that folder, there should be a wallet.dat file.
If you have currently no bitcoins in the wallet, you can just delete that file and replace it with your backup wallet.dat file.
When you placed the wallet.dat file in place, you should run Bitcoin-Qt. Here's how to do that in Windows:
Now Bitcoin-Qt should start and rescan the blockchain to calculate the balances of the addresses in your wallet.dat file.
