Michael Saylor buying $500m or even a billion with his strategy.
How to know when has he entered in the buying spree by looking at the price movements or charts?
from what I've noticed, Michael Saylor buys Bitcoin at an unknown time...
basically, he buys Bitcoin when the market is down, his only goal is to spread public confidence to buy Bitcoin too. recently when the market was sluggish he bought more Bitcoins, from there we can know his buying habits.
