It would shrink, definitely, but as the other two it wont disappear as it's actually required, both as protection against inflation or also as a fast and no-middlemen way to send money. And for specifically for bitcoin[1] the "goal in itself" is the anti-inflationary part. Nobody wants to lose what they have because somebody else thought that creating new money is a good idea. Putting your cash into other assets such as real estate achieves the same goal, bitcoin is just more convenient. [1] I say "specifically for bitcoin" as what a value of any cryptocurrency is depends on how it's actually coded up (how/when it's created, burnt etc). Not all cryptocurrencies are good for "stores of value".
