In the past, 33105 $BTC were moved from a wallet that came from Mt Gox wallets and was thought to belong to the BitGo exchange to a newly opened wallet.

A certain amount of#BTCwas also added from separate wallets, the mentioned wallet currently holds 33023 BTC

I found it strange that it was combined with BTCs from other wallets, I will look into their history
