At this point, there is no known better believer in Bitcoin than Michael Saylor except the founder Satoshi. History will remember him as a key figure in Bitcoin and the wisest investor of all time. He was firm and resolute even when many people were doubting Bitcoin and he still remained resolute and motivated to continue to accumulate Bitcoin irrespective of the price. What we can do is follow him because there is something he sees in Bitcoin that majority are not seeing.
Definitely, he is a believer of this currency. And with such bold move, for sure, he is already reaping his rewards. I don't think he is confined to being a bitcoin investor only. More than likely, he has a lot more when it comes to investments. As he needs fallback when things go awry in this market. He won't stake so much on this market if he doesn't have contingencies on the side.
