Guys, I have another question.

Could anyone please explain to me what's this first wallet address for???

The wallet that received 0.000072 BTC at the below link:

https://blockchain.info/tx/54b06735a6e226dc6bde907ebf328413d529a5d30a6700a118579db4e9cf2914

I understand the other 2 wallets, I don't understand whose is this one though.

What is this amount for and who received it?
