Bitcoin will hit $500,000 & beyond but you have to be patient. Bitcoin is a get rich slow investment. It will happen but you are not going to become a millionaire overnight. Buy Bitcoin regularly for many years & you will be very comfortable financially in 20 years.
Getting rich from Bitcoin requires long-term investment. If invested for 10 or 15 years, that investment will give 10 to 15 times more profit. So those who have enough dollars will invest in Bitcoin and hold it for 10 to 15 years. Long term investment means future billionaires.
In other words, Bitcoin is like most profitable investments that requires time to mature and yield rewards. Truly, no long term buyer that ever regretted purchasing Bitcoin. Those who do, didn't have the patience to continue holding, and as it works, they'll go back to see how much their sold btc is now worth in recent market value. For instance, the proposed US government bitcoin reserve is based on a 20 years interval, because it's rare not to see significant changes in price after holding btc to that length of time.
