Okay good read from the xapo. To be honest to reach the market of 500K USD per bitcoin it seems little deceptive because of the one and many facts that are related to bitcoin and its acceptance in the world. Bitcoin as we see today is all grown because of the investors who were investing into blindly some 7 years ago and they became the richer. However, in todays date we have crypto people who are just fluctuating the market to get the quickest profits form those artificial pumps. Bitcoin is growing naturally no matter about that but when people see some good reason to sell high then they will do it predominantly leading to down ward movement of the bitcoin.


So this is restarting factor one to make bitcoin that much worth by 2020. Im not saying that its completely impossible but not possible that faster. Apart from that it will need huge market capitalism to have that much sufficiency of delivering the price equal to 500K USD.
