Imo this second death cross is positive for Bitcoin. But if people don't understand math is useless to explain how works moving average. In short term: if the 50ma falls fast and no longer approaches the slow one, then it is a confirmed bear market, if the 50ma is close to the slow one, then it is close to a bullish move.
But basing everything on a single cross is useless, the situation can change.
For me, now nothing is changed. February will tell us.
