The analysis you cite is flawed for 3 reasons:
1. It conveniently ignores the first bubble to $32.
2. If that analysis was performed in early 2012, it would totally miss the bubble to $266 and $1200.
3. During the bubbles, bitcoin was neither linear nor exponential. It was parabolic. But in very long term, the exponential model still gives the best fit. The R-square for linear and exponential model are 0.537 and 0.888 respectively.
This thread is for people with long-term interest in bitcoin. Not for day traders. By long-term I mean at least 2 years of patience.
1. Bitcoin was in its early days, a price of $2-32 was relatively low and was a easy target for penny stock pump&dumpers. Bitcoin at $2 (its marketcap) was easily pumpable. At $500-1000 or now, not at all.
2. The slope of the two trend lines is totally different. The 2011 trend line was way too optimistic and you couldn't really think that the price would have stayed above such trend line for long, whereas the current log trend line was a reasonable target and could have been easily followed assuming an exponential trend or a long term bull market.
3. The current log long term trend line that was broken is a multi-year support trend line (3 years) while the mtgox 2011 trend line was barely 1 year.
4. Bitcoin in 2011 was an obscure experiment, today is an asset known and watched by big players (even tho the majority of them are smart enough to stay clear from it apparently...), if nobody gave a fuck when price reached the trend line in 2015 after more than 1 year of bear market and it broke with a spectacular crash, it means you can wave goodbye to your long term BTCullish
What a lot of people here are saying is that, since in 2011 price broke a log trend line but recovered with new bubbles after that anyway despite the fact that the 2011 chart looks like a textbook penny stock pump&dump, CURRENTLY ANYTHING IN BITCOIN CAN HAPPEN AND A NEW BULL MARKET COULD BE AROUND THE CORNER NO MATTER WHAT THE CURRENT CHART IS SHOWING US.
Thinking this is just dumb in my opinion, don't you think?
