is that a valid recieving address? you need to download a wallet and generate a seed. Seed is your key. Make a new one and dont share it with anyone:) its like your wallet password^^once your in the wallet just generate address and attach to tangle. The address that you generated can be shared. Simple:) Here you can download the wallet: https://github.com/iotaledger/wallet/releases
