My worst memory was when half of my existence disappeared in one day. If you remember there was a sudden drop last year, bitcoin suddenly dropped 30 percent. It fell again the next day so I lost most of my money.
What do you mean by half of your existence? Was it money or your self-consciousness? But, it could be true since many of us can easily trust a thing and we put most of our life savings with it. If you just joined last year then that might be your first challenge in bitcoin but I think there are years where the dip is worsen than that.
It was this year actually when btc drop more than half of its price but last December I think the lowest of btc was only $40k to $50k. You may lost most of your money but that is only temporary as long as you didn't sell your bitcoin. If only you will hodl it and wait for the market recovery then you will be just fine.
