Bitcoin is never going to be extinct
I believe its consensus will be higher and higher in the future.
I dont see anything that will ever make bitcoin to go into extinct because it has a very strong root already and has already been able to win the heart of many strong communities that are using it for their daily transactions, and people are beginning to rely much on this system for easy payment and also this is still the most profitable trading currency that is better than that of Forex trading.
We are just gradually winning the heart of so many agencies that are beginning to be willing to invest in bitcoin now. Starting from the nest halving, I am sure that there will be more adoption of bitcoin because there will be a big hype then that will also make the rise in the value of bitcoin to attract more users and more investors of bitcoin to the crypto market.
