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. 
I have no doubts about the development of bitcoin in the future, but the cycle they have gone through does not provide a guarantee in the next 15 years bitcoin will reach a price of 1 million US dollars, many cryptocurrencies are emerging today, although none of them can replace bitcoin in crypto , but anything can happen in crypto, even if it can't last as long as bitcoin is at such a high price, but I doubt other cryptocurrencies will reach that position.
