This is certainly not the end of cryptocurrency, it is a simple manipulation because remember yourself at a time when bitcoin and all other coins grew, everyone said it was the future, that bitcoin would cost 50,000 and now when the market fell, everyone says its the end of the market so dont pay attention to this.
If you don't want to lose your money better to assess and decide with your own knowledge and trust, those speculations can be use as a basis before you decide your position, the market still being played by big holders and manipulators, the more we react according to their plans the more they will shake the market so better to prepare yourself.
