Can any of you check the balance in my wallet, please? or any way to check it online
Otherwise... the best/safest option is to simply let Bitcoin Core finish syncing... you won't accidentally expose any private keys and you can be assured that whatever the balance displayed is when finished is correct.
Also, please don't create new threads when you have identical ones already posted: https://bitcointalksearch.org/topic/m.56598378
It creates confusion and splits answers across the threads. You would be advised to lock one of the threads and stick to just one.
