Well, it looks like someone has entered the wrong address here, or maybe you have a certain relationship with the owner of the account, or maybe someone who is kind enough to give some Ethereum to you, but clearly you might be lucky, so use Ethereum as good as possible
I would agree with that opinion, but he had these ETH till 1100 days back, and he started distributing yesterday? Also most of the other transactions, continued automatically to Binance or Bitfinex, most of them in the same time, in a matter of an hour. Something's happening here.
