Arguably one of the biggest bets on $BTC is being made by Michael Saylor. Hence it makes sense to monitor his movements on the market. There are some interesting metrics that can provide an idea.
Especially the correlation with $MSTR provides some insight. The chart below shows that, Saylor likes to buy Bitcoin when premium of $MSTR is above 1.8 and holds off when premium sinks below that mark.
That indicates profitability as long as premium stays at these current levels.
Means, currently we are holding around 1.8 level: Very likely that more big buys are incoming.
