Today I watched a movie "NERVE" , after watching that I got to thinking about how cryptocurrency transactions work ,

**Spoiler Alert**
The movie is about an online game, when everyone logged out from it the game completely disappeared.

So like that if everyone stopped mining bitcoin at one point (this is much unlikely, but worst case senario), what will happen to the Cryptocurrency market, will it completely vanish, like it never existed? 

Copper membership = Benefits of MEMBER rank , including applicable Member rank signature code, can I join Member Level signature campaigns as a Copper member? even with Newbie or Jr.Member rank?
