When the bitcoin price was stuck at the $220 - $280 range.
From early Feb to mid October 2015 (for almost 9 months!), a lot of people were quite impressed with the BTC price "stability". Some were excited about it because BTC looked more reliable as a currency. For some, it looked like that being "stable" would give Bitcoin more credibility while others were disappointed and bored with the lack of volatility.
Then after that long period of "stability" it quickly jumped to the $400+ level for another 6 months. It was a hard and slow time for BTC (and most alts) as the glory days of Nov 2013 were just a distant memory. I clearly remember a friend telling me at the time, after taking a small profit, that there was no way he would pay $400 for a bitcoin, it was too expensive and he would wait for a correction before jumping in again. Unfortunately for him, a correction down to that level has never happened.
Back then, some were quietly and steadily accumulating it while others were selling it because it looked like it was going nowhere.
This is just food for thought and I'm not going to tell anyone to HOLD their ETH based on past events. I hate telling people what to do and the market needs fuel to take off.
