You don't understand me. I'm speaking about "the experience economy" theory and about consumer choice, not about coffee or hamburgers.
Altcoins are created for many different reasons and things. But we are talking not about for which reasons their original devs have created them,
but will people use them, or not, will people spend them, or not, will people buy goods or services with them.

I don't mean altcoins like altcoin of runners, altcoin of aquarium fans, altcoin of coffee lovers etc.

An example: DOGE was created for fun. The question is will DOGE lovers use Dogecoin to buy goods or services, or they will use BTC alone.
My answer is yes, they will use DOGE.
