I just checked on blockchain. It shows proper balance on one of the addresses which I have in my wallet. Though it`s not the one which I used to receive money, but the one which is staying in the wallet under the title "change". Is that normal? I don`t know why is money moved from one address to another.
Change addresses are used with the purpose of rotating and to avoid the reuse of addresses when you do a transaction. When you send your BTC from the Electrum wallet, part of that is sent to the receiver, and another part is sent to a change addresses.
This is done because reusing addresses is bad for privacy and security (third parties can monitor your transactions easily).
