If bitcoin reaches gold marketcap 6.6T, the price of btc will be 330K$. We all know US has got 334B $ gold reserve, but doesnt have any bitcoin yet, maybe have 1000+ coins.
I guess bitcoin may rocket to 100K+-$ in 2021, and this cycle will be the last bull cycle, but will fall down to 20K later. After 4-8 years bitcoin will stay at 100K$ level, then move up little by little to its destiny.
2069 AD, Bitcoin will step slowly up to 1M $, if it finally defeat US dollar and become the first reserve money in the world.
