Market cap means nothing. I can create 10^32 coins out of thin air, sell one coin at 1$ to one customer. And the next thing I have is a coin with higher marketcap than bitcoin.
Even if 1 client per year buy it (let's say my token purpose is to give to access to private content on my website), then my marketcap is still 10^32 $, because marketcap is just the number of supply x the last traded price of my coin.
And yes, we both agree, marketcap has 0 value. It was just to make a point that using the marketcap as argument makes no sense.
What about the people who try to sell it after buying it? If they have to sell it for 10^-32 $ before someone buys it then that immediately drops your market cap to just about nothing.

No, I just explained why marketcap correctly values your coin as absolutely worthless.
