Updating, since the x10 exponential growth is, obviously, over, and we seem to be reverting to the x4 baseline growth. That line now offers support at $180, so if the previous ATH at $266 falls we could still go down 60-80$ to bounce off the long-term bottom line.
Just for some optimism, that bottom line crosses $300 at the end of January 2015, and $1200 at the end of January, 2016. For a historic reference, that bottom line was not once breached in bitcoin's history, even in flash crashes (mtGox hack does not count). But we did deviate from it quite a lot in 2013 to the upside...
I posted similar trendlines in the german coinforum.de
https://www.coinforum.de/topic/2706-bitcoin-chartanalyse/?p=46540 Mt.Gox does not count ,indeed,since it was a classic dead cat bounce.
The only weak point in the bottom trendline is the fact,the confirmations (about 5 ) occured in the early beginning of that bottom line.
Since then no testing of that line happened.
So we will see what happens if the line is tested again
But as long as the fundamentals are very good I am not scared.
And these fundamentals are still very good.
