As of right now, the bitcoin price is expected to keep going up in the next 20 years. But can it last that long? I believe it's possible. But can't it crash at a random time? Like the price going down hard.
There is no definite time until bitcoin would last. No one can predict how long it would be visible in the market but i think it would last longer. Crashing of the value of bitcoin is also indefinite for as long as the investors invest and believe in bitcoin the possibility would still increase and would not crash.
