The chart &pointers were inspired by this article https://medium.com/@100trillionUSD/modeling-bitcoins-value-with-scarcity-91fa0fc03e25 and it has plenty of rich information, it's a long read just hang in there
Pointers I felt hold water:

• Bitcoin by the year 2020-2021 would be trading @~$55000 based  On btc halving, and according to the author money will come from "silver, gold, countries with negative interest rate (Europe, Japan, US soon), countries with predatory governments (Venezuela, China, Iran, Turkey etc), billionaires and millionaires hedging against quantitative easing (QE), and institutional investors discovering the best performing asset of last 10 yrs."
• Bitcoin SF soon to catch up to that of Gold
• possibility of achieving a $1trn market after the halving in May 2020
• "Bitcoin is the first scarce digital object the world has ever seen"
