Today, many people involved in crypto currency understand the fundamental difference between bitcoin and another crypto currency. Therefore, if bitcoin for some reason suddenly disappears, in many ways it will depend on the cause of its disappearance. If it is associated with drawbacks of bitcoin, this should not affect the continued existence of another crypto currency. However, in the event that the disappearance of bitcoin is associated with the general shortcomings of the crypto currency, the reason for such a shortcoming will be of great importance. In general, given that even today there are a lot of various promising altcoyins, they will continue to exist despite the lack of bitcoin.
