I created a Bitcoin wallet yesterday using Bitcoin Core Wallet application and bought some bitcoin via buy.bitcoin.com to the address mentioned in File>Recieving Address in my Bitcoin Core Wallet. They sent the money but I can't see if I received it or not because I did it before synchronization complete and it seems it takes at least 2 weeks for my bitcoin core wallet to finish synchronization (I think the number is increasing):
Is there anyway I can move my wallet to some other bitcoin client and start using it instantly? I paid a lot of money to but bitcoins and it seems I can't use it until this app finish its synchronization.
If so, then which client and how?
Any help/guide will be appreciated.
