How much will 100k be worth in 30 years?

Could you please elaborate on how one might estimate the future value of 100,000 units of currency, let's say in 30 years' time? What factors should we consider when making such a prediction, given the volatile nature of cryptocurrencies and the ever-changing financial landscape? Would historical trends or expert opinions be more reliable indicators? And how might technological advancements or regulatory changes impact this projection? Is it even possible to provide a reasonable estimate, given the inherent uncertainties involved?
