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.

In the next 15 years, for the price of Bitcoin I'm sure it can penetrate as you say, 1 million dollars, it is possible for Bitcoin to achieve it all, we are back in 2009 and 2021, one reason that can be sure is most likely to be achieved.
15years is really a long time to forecast what's the probable price, but ofcourse bitcoin will always stand at the pinnacle amongst other cryptocurrencies and it will surely survive unwithered even at the time of our grandchildren's sons and daughters. But 1 Million USD prediction in 15yrs from now? It's too long and far to predict, but yes, who knows right? Bitcoin is always unexpected and maybe it's possible to reach that price.
