Bitcoin Core frozen trying to sync and/or connecting to peers I downloaded Bitcoin Core directly to my laptop and sent BTC to what i believe is my wallet. The BTC is no longer in my senders wallet and I do not see it in my bitcoin core wallet. It was working slowly but now it is frozen at 12 percent.
Your wallet will need to sync to the network before your funds will be shown as available. This is because the ‘sync’ process involves your node verifying the history of transactions, so the transaction you received cannot be verified until all other preceding transactions have been verified first. 

If you think it has frozen during the sync, I’d suggest turning the debugger on, and then looking at the debug.log file for clues on what the issue is.
