If you have a limited supply of currency in a growing economy, it's inherently deflationary. So far I haven't seen proposals for cryptocurrencies that can grow as a function of the underlying economy. Maybe there are some.

All current attempts at cryptocurrencies, of which there are very, very many have been inherently deflationary. Can you point me to a single one either current or even planned that isn't? We are discussing the real world.

Both Ether and Monero are uncapped and deflationary. So 2 out of the top 10 at the moment. I didn't bother checking beyond that.
