... the number of total investors has increased exponentially. ...
i am very interested to know how did you measure this?
i mean there is no way of knowing how many people have invested in bitcoin because there is no centralized entity that can release statistics about this so we can make a conclusion and the stats we get from blockchain as the public ledger are inconclusive.
My thoughts exactly. It's all guesswork mostly. Yet it feels like more and more people are getting into it.
