am not sure if bitcoin will survive that long , because there will be surely another currency that will make its way to the top as there are many issues bitcoin network is facing and if all of those leakage will be covered by a new coin then what will hinder to break bitcoin position and bring this once great coin to the lowering position.
We can only say with certainty that in a hundred years everything will change very much. Including cryptocurrency, if it still exists by that time. Bitcoin will probably no longer be in such a form as it is now. It is impossible to even say what the cryptocurrency will be like by that time. We see how quickly it continues to develop. New directions are emerging that we did not even know about. So for now, we will be watching this market and working on it. From a practical point of view, it makes no sense to think so far. After all, we will be gone by that time.
