Bitcoin is never going to be extinct
There is no such thing as forever in this world and all things will eventually end but there are those which exhibit long-lasting qualities and I am expecting that Bitcoin can be a part of that list. As long as there is a good demand and supply, I think Bitcoin will be doing fine and we will continue appreciating and making Bitcoin popular and widely used. Nobody can be sure of the future. With the way it is right now, Bitcoin could not survive due to scalability problem so let's hope that acceptable solutions can be found for many challenges that Bitcoin is facing. As long as there are people like us who love to use and trade Bitcoin, then this coin is not going to be extinct, definitely!
I believe its consensus will be higher and higher in the future.
You must be talking here of the price of Bitcoin, am I correct? In the near and far away future, as long as Bitcoin's demand is increasing its price has the chance to also continue expanding though it is not going to be on a straight line. The history of Bitcoin has been littered with many surprises and unexpected stories so it will be the same for the next 10 more years. There will be small and big dips, crashes, bears, bulls and many things in between. Just continue on hodling and soon you will be rewarded.
The bitcoin market price will always be affected in the market the supply and demand of bitcoin and the supply was moving fast. Bitcoin popularity was already rising so I don't think the bitcoin was going to be extinct in the coming years I think the bitcoin was just starting to immerge in the society and use it as digital cash. The government, in my opinion, was just starting to adjust and adapt to the bitcoin environment so eventually, I think bitcoin will be part of the society. It will never be extinct thinking it already build a market and investors.
