Money. I don't think Blocktrail gives a shit to what Bitmain does with it now, I am sure they all made a nice profit.
Money for Blocktrail. But, how does it help BTC.com aka BitmainTech ? Why did Jihan spend money on it is question to me.
Well I don't know the specifics but companies usually y reduce their tax by reducing their profit. Investments that seem on the face of it to not be logical could be for this kind of reason. Time will tell if they have other plans.
