We don't need any newbies for the price to go back up. In fact I'd say in the last run-up, up until the 1200 ATH, there were not that many newbies coming into it at all. Mainly just the true believers buying their coins as usual. The newbies are what create the bubble, they probably only really started coming into it a few months into 2017.

Eventually the true believers eat up all the sellers coins, and then the price slowly goes back up as only the miners coins are left to purchase. ATH breaks, then come the noobs.
