There could be a drastic change under way. That's what permabulls don't realize. Until the 2015 lows are broken, it's still officially an uptrend and bulls can cling to that. The trend is your friend until it ends. Of course, there's no guarantee the trend will sustain forever. That's why I think it's important to always take some profit out of the market during bubbles. If Bitcoin fades away and heads back towards $0, it would be a damn shame to be a hodler and give back all your unrealized gains.
