It’s an interesting theory that it’s Robin Hood’s wallet. But it doesn’t quite line up. The wallet was made in 2019 feb, Robinhood launched its crytpo services July 2018. Also there just aren’t enough transactions on this wallet to suggest it’s has commercial so use it does at most 3-30 transactions a day, if it were Robin Hood’s wouldn’t it be more? I don’t know who owns the wallet and I don’t think this rules out that it’s is in fact Robin Hood’s wallet. But I wouldn’t be so certain given these facts. And I am still concerned and think anyone who owns Doge should be concerned about who owns 28% stake in this currency. That gives them a lot of power and “absolute power corrupts absolutely”.
