Bitcoin reached more than $10,000 last year if you didn't saw that.
Today there are 17,000,000 Bitcoins in existence
Nope, we just passed the 17M supply and the total circulation now is 18.1M bitcoins in circulation. With the valuation you have for bitcoin to reach $100,000 within 20-40 years, honestly it's very realistic but I think we should in the middle because we might see more than that during that period.
