I have a serious question for the crypto skeptics out there. Is it possible for Bitcoin or Ether to ever tank completely? I mean, investors often complain about volatility - but investing in crypto as a whole seems fairly low-risk compared to most other investment options. At worst, it may lose value down from buying at a high, yet the best-case scenarios are all extremely good. So low risk of loss and high probability of gain. Is this misguided at all?
