It's the same as bitcoin. Your wallet does cointain more than one single receiving adress.
Blockexplorer only show you one adress.
Go to receive tab into your wallet and you will see there are more than one adresses
I did.. one address only. I thought the same thing... like the new btc wallets generate a new receive addy all the time...
He's just is a long term investor... not too many transactions.
