After all the hype, does anyone have information on this? I reckon blockchain analytics should follow those coins of the new VIP of the bitcoin community and follow the movement of their coins.
This is quite impossible to know that where they store their Bitcoin. Because they store big amount of Bitcoin. If they public where they put or store Bitcoin then it is not much secure because some black hat hacker try to steal it. I think they use much secure wallet and some guys help them to secure it from any danger.
