also the first bitcoin market was the first bitcoin exchange. and coinmarketcap is not an market or an exchange. its just a flawed stats site.
i was going to give you a tough lesson in economics about bitcoin(again) and also a lesson in the real estate market(your analogy) but i feel you dont want to understand and are just looking for people that want to agree with you, where you are not looking for facts or corrections to your opinion
I will give you a simple lesson in economics. There is no such thing as a residential real estate exchange. But the residential real estate market exists. The second example is even easier: there is no such thing as a plush toy exchange, but the plush toy market exists.
