yet markets did not move to any bad degree.
Well, Microstrategy made their biggest purchases in the 2nd half of 2020 (a series of buys totaling over 70k bitcoins) which was in line with the beginning of the biggest bull run, so it's hard to dismiss they might have had some effect on the price.
They were buying OTC so the timing of the impact on the market could've been delayed and it's way harder to measure it.
A full record of their purchases, if anyone's interested, can be found here: https://buybitcoinworldwide.com/microstrategy-statistics/
But yeah, a single buy/sell of a few thousand is not something to get excited about.
