I have found an old bitcoin wallet in my files. I can see there are old transactions but they aren't confirmed. But there should be more BTC received than was sent, so there should be a balance. Is there anyway to get those transactions confirmed from 2013. And how do I check those addresses to see if there is any balance in those wallets?
To check balance, just use this link: https://blockchain.info/address/your-wallet-address-here to check the balance of any wallet. You can also see all the transactions happened through that link.
