@morganc, whatever you do with those 10 BTC, never accept any advice you get on PM or via an email posted publicly on your profile - the world is full of scammers who would be very happy to help you stay without those 10 BTC.
@ETFbitcoin, I remember the OP mentioned earlier that his wallet was from 2011, and if we assume he didn’t move the coins to the new wallet, it’s a little weird that after syncing he still has 0 on balance. The only logical explanation has already been mentioned by @nc50lc - or maybe there is some problem with the old wallet -> latest version of Bitcoin Core?
- In early 2011, a friend introduced me to Bitcoin and got me to setup a wallet and then transferred 10 coins into it.
- Until recently I thought I had lost the file, but by chance a few days ago, I found it on an old USB stick.
- I then installed the Bitcoin Core / Qt software that was on the USB stick and copied the wallet.dat file into the folder
- over the last couple of weeks (using an old laptop), it has synched and confirmed that there are 10 bitcoins in there ... wow ... yippeee !
However, we can see the key difference here, the first time it was weeks, now the OP claims that it is only a matter of a few hours - maybe you are right after all.
As a suggestion in case the transfer wallet.dat still gives 0 balance, there is always the option to dump private keys and import to another wallet - but since it is 10 BTC, I advise maximum caution.
