Nobody knows the answer for sure but its worth researching and getting into with a small amount of money that you can afford to lose.
This is some what accurate, people who invested in bitcoin in the beginning took a risk because the price was really low, will people risk investing in it when the price of bitcoin is $9k, will people take risk in investing in it, i really do think that it is late to invest in bitcoin if your intention is to make profit, but if you are planning to use it as a currency, there is no time to invest.
