The question is very much arguable; many will present their facts and reasons for why they chose the answer they chose. Currently there is no asset that has proven to be competitive with Bitcoin, so we can say that Bitcoin will sit on that throne for a long period of time.
But we are in the era of change, where new impressive innovations are welcomed and accepted. If in the near future there is ever going to be a new asset that will fill in the gap that many consider to be very important, then there will be a shift in choice, but that's not going to happen anytime soon, not even in the next few decades, but in the near future we should be ready to accept change.
Even while it is a matter of it may happen or it may not happen which is probability I agree with that there is nothing absolutely wrong in thinking in such directions and at the same time and of course have an open mind to accept changes which we all know is a constant factor while in the main time our focus should be more on how best to utilize what we have now and have proven to be best without struggling or overthinking about the future of such, if am not mistaken I think we have seen similar threads in this forum, our attention should be given to Bitcoin for now because it is still the kind on that thrown that we know for now.
