People talk about not losing money until you sell, but it's a double edged sword. That same logic implies that you haven't gained any money until you liquidate your position either. Honestly the best way to look at it is that when the price goes up, you make money... and when the price goes down, you lose money. Your gains/losses can change constantly, but selling will cause that to stop, effectively locking in whatever gains or losses you have.
Just because you plan to wait a long time before selling bitcoin doesn't mean you have not lost money over the past month or so. Everyone who owns bitcoin has been losing money recently.
When the bitcoin price started to fell down from huge price since last year are experiencing losing money on bitcoin. Most of us has losing a lot because of this current situation if we cut loses another huge lose. The best that we can do in this moment is to hold the patience that price of bitcoin will swing to rise up.
We'll only lose if we sell ir, jist put patoence and now that somehow it will increase too like it always did before, it's jist a correction.
