when I got into mining oct 18th BTC was $150 usd ..then imho the china bubble ( a lot of Chinese trying to get 40 years of wealth out of china they could not do previous
in the form of BTC asap) and the authoritarian crackdown in 2014 from China and other countries on crypto and BTC and the bubble pop'd with the above and also
speculation was involved ...add mt. gox and other scandals and it is kind surprising it limped into 2015 to tell you the truth...

now it is 250 for btc more or less

if next year it goes say 350 etc that works for me too ...but BTC also will work as protocol for moving wealth world wide from 'not so enlightened' countries due to greed
war corruption etc to safe havens without banks/gov't involvement....that will come first...then as a method beyond this protocol the coin price will be based on how useful this network is for doing such..that perceived use will determine coin price for the next 5 years imho with hopefully adoption ticking up ..but adoption will tick up on the hopefully working
protocol and hopefully good press on the above working as I state (knock wood)

folk adopting something that they see in press and elsewhere as having a legit and unique use and the fact it is open source etc would go a long way to easing any fears
on price..the old saw "now I get it" then to 'lets also buy some btc' ah ha moment (i hope)

anyway badly explained but how i see it ..kinda sorta in a rough kinda way..
