I mean if you are trading in uptrend it is quite easy to buy low and sell high but what are you going to do when it's all low?
Not sure if that's the case.
It's way easier to make money on the way down than on the way up for me. Bitcoin has always been extremely unpredictable when it comes to its increases, while after a bull run it historically goes down with ~75% form its peak, and it happens time on time again. The 2014 bear market trapped me in like a noob, but this time it's different, and I hope it's the same for the people who got trapped in currently. Bear markets make strong future hodlers. What can be worse than going through a 75% decline?
Tip; if the price ever is going through a bull run again, make sure you short a small percentage of your Bitcoin with a 2x leverage (don't recommend higher) and leave it open till you think the bottom is in. It could be seen as insurance for your investment, because the lower the price falls, the more you'll profit, and the more bearable it is for you.
