Market cap makes more sense for a stock, because it's in the range of the value for a company, and a whole company is something that does get bought and sold. This idea doesn't make any sense for a crypto. 

I always wondered about that. Especially since people (and hucksters, trying to sell their wares) refer to Bitcoins as crypto currency.

I'm not a financial wiz kid, but market cap for a currency doesn't make any frigging sense to begin with.

Sure, you can count the amount floating around for a currency on various levelse (ususally expressed in mx) but I never felt that it makes sense to define this as "market cap".

The whole situation really reminds me of the Dutch tulip mania (https://en.wikipedia.org/wiki/Tulip_mania, the first speculative bubble in history).

At least with your "investment" there you were able to plant pretty flowers. Here, I fear, that a lot of small investors will get burned very, very badly.
