Cryptocurrencies do generate rent. You can lend them and collect interest on it. Houses don't grow in value because they generate rent - they are deteriorated by residents and need permanent investment in repairs to hold their value.

Likewise, if more merchants accept a coin, the coin is more valuable because its more flexible.
