Price on any instrument always tests previous highs .

April /9 /2013 previous high before we hit $1100 was £260 ish ,we retested it jan 14 2014 .

November/ 1/ 2015 high of $500 ish was retested july 31 2016

June/ 16/ 2016 high of $778 ish was retested Jan 9 2017

You can verify these facts on bitcoinwisdom open a weekly chart the levels are clear  to see .

At some point $1100 ish will be a previous high that we will retest .

Considering some of the very large individual trades I have witnessed on bitstamp I have a strong inclination to believe $1100 will be a previous high within months .
