1) Some people are asking how Micro Strategy got so much sell-side liquidity.

One thing that's been bugging me is that Micro Strategy bought $425 mil and price really didn't go up much. I'd honestly expect price to do anything but randomly drop/chop sideways after an event like that.

2) it was ~$400m. How much impact does that have? Hard to know for sure, and it obviously depends. On March 12th, ~$1b of liquidations probably had ~20% of impact. That's terrible execution at a terrible time. BitMEX has ~$20m/%, which lines up.

3) what if you do it slowly during a quieter time? Well, one quick and dirty estimate: impact ~ daily vol * sqrt(size / ADV). Here, that's roughly 1% * sqrt($400m/$10b) or so; so maybe like 1% * 20% =.... ....0.20%? That's 100x lower!

4) alright, how about in practice? Well, my totally bullshit instinct, based on nothing, is "idk, 5%?" So if you do something that has 5% impact over a few day period on BTC... ...if you're not looking for it, you'd miss it. If you *are* looking for it, it's obvious though.

5) does anyone know when they bought? How did BTC perform those days? How did ETH perform? Did BTC do worse than ETH?

who ever plays around with the price, just lost 400 millions ;) to these guys. is it much? for them not really. the question is, are they able to secure the rest of their liquidity to not get bought up also?

and I also don't believe that this kind of transactions are not forseen by exchanges and OTC-services. they have to transfer Theter to an exchange according to this 400 millions. So as soon, as their trading account starts buying these ammounts exchanges know this, or not?
