What is our assurance that Bitcoin will stay for long or forever?

What is our assurance that Bitcoin will stay for long or forever?  There is a prophesy I have heard that Bitcoin will fall.
Can you share some strong reasons of why Bitcoin will last?

Bitcoin won't last forever there's no such thing as forever. Every crypto will have it's end but we don't know when. One assurance is Bitcoin's security. Our technology is not powerful enough to brute force in to someone's key and steal their coins. Attacking the Bitcoin network would be costly for anyone just to have the power of double spending in a day or two.

Nobody can predict whether how long bitcoin could survive, there are a lot of people keep on spreading fuds, and some big investors keep on saying bitcoin is bubble, but one thing that make me sure bitcoin could survive longer, which is the adoption of some countries, when there are still people using bitcoin then bitcoin will still survive, if more companies adopting bitcoin, its mean bitcoin growth is good and could survive longer

It will stay for long in my opinion as long there are still more investor that always grab an opportunity and still enjoying with it to earn huge profits. And it will ends only ones there is a new crypto coin that has a potential as well to take over its place. But it's impossible because bitcoin is the king like what other said so no one can overtake on its place,  unless if there's a collaboration to leave IMO such big investors which is has a big contribution in the growth rate.

I don't think that there will be a clear guarantee that you must be able to have the courage to do something and try new things to be able to keep making money and can help your life, before you have to know that bitcoin has a very high risk.

Fall doesn't mean the end. Bitcoin is like a roller coaster sometimes went up and sometimes went down. There are instances that we think it will crash to the point of death. It is just a presumption but not the reality. Bitcoin killed 100x yet it is still exist.

Less prescient investors, fearing they’d miss the opportunity of a lifetime, had jumped into the currency, spurring a frenzy. “If Bitcoin is successful, the opportunity I have, my son will not have, and definitively, my son’s son will not have,” says Martin Garcia, managing director at Genesis Trading, the only licensed U.S. broker-dealer for Bitcoin.

The fate of Bitcoin depends on how competitive it will be in the future. So far, we can say that it exists in the lead in credit due to its former popularity. However, if he does not improve and eliminate his shortcomings, he will quickly lose his leadership. However, in any case, soon he will lose his level of capitalization, because new altcoins with new technical capabilities are rapidly developing.
