with all these huge bitcoin purchases by corporations, i was wondering how many bitcoin is left in ordinary ppl's hand and i made an assumption which ended up w/ this number:
7,137,213 bitcoins + 900 (newly mined per day)
is this method proper for a close guess?

bitcoin_in_circulation= 18,630,338

nakamotos= 1,100,000
