BTC has entered the second 4-year halving cycle and will rise to 1 million U.S. dollarsin the next 15 years. What do you think? Friends are welcome to discuss together. 
Next 15 years is so long to predict but if we can see all countries goes digital currencies and they will choose bitcoin then we might gonna see this happening. But for sure each country will create their own digital currency and bitcoin will be just another option to them so maybe the preferred figure to be reach is still 6 digit number if bitcoin will still alive 15 years from now.
