Why call it a "Crypto Crash"?

Things without value cant crash just return to reality, and we are still far away from the true abyss for Bitcoin. $Bitcoin (BTC.CC)$

Bitcoin has no underlying value and no underlying asset. Bitcoin is not a company that can regenerate investments. Bitcoin has no underlying asset that people needs like Silver, Gold nor Oranges or Pork bellies. Bitcoin is just a transfer system of "real" money. However this system has huge maintenance costs and in the end systems that cost a lot of money without REAL return dies.
