That might be true. The problem I see is that we would have a highly dysfunctional market then, even just for a very short period of time. But one basic requirement for TA is a functional market. Especially wave counts and stochastic bandwidth approximations like bollinger or Ichimoku don't work correctly then and lose reliability.

BTC has never touched the bottom BB band on a monthly scale, much less go below. It would be catastrophic. Unlikely.
