If it couldn't hit 30k in January the chances slip dramatically as time goes on. 2018 ATH would require a 2013 style double top. Pre-requisites for this action:
New far greater wave of speculators
-> Coinbase was already the #1 app, everyone rich country has exchanges, it was on TV every night. There is simply no fresh pool of suckers, that is why the price topped out, we ran out.
New wave of big money
-> The worlds smartest and biggest investors are not going to load into a bear market, why would they buy something now for 10x when they were looking at it earlier.
Old bag holders break free
-> Everyone who got burned has to get out and get even or have sold and taken their losses. This places a huge ask on top of prices holding it down.
Seed -> Sapling -> Full Tree
^ All of these are do-able, each jump becomes more difficult. Going from .001% of the population knowing about BTC to 1% means an enormous price increase. Going from 50% to 80% is impossible, 50% of the population can't name a single senator, nothing will be able to reach them until it reach Visa level. (40 year build out requiring the coordination of all the worlds banks, massive marketing campaigns, actual utility)
We only wait for the whales pump again, I'm sure this will happen soon before August, I get a lot of news that dumped is happening right now is a whale strategy to get cheap price.
