I compare the invention of cryptocoins or blockchain to the invention of the combustion engine. It just opens so many doors to new technology. I don't see my crypto wouldn't be adopted by the masses as a payment method at one point, since the advantages are just superior compared to FIAT. If you save up 10000 $ over the next many years, they will be worth nothing at all when you want to use them. Of course there are other methods of avoiding inflation, but IMO crypto is by far the most practical solution.
