Let me briefly mention BTC. BTC56000 is just the first support. If this position cannot rebound immediately, it will continue to fall. The next support is still 53500, and even lower 49000, 46000...
Don’t think that this kind of negative decline structure will slowly fall like in the past and grind near the support for a few hours. I think BTC has not experienced a sudden collapse level of big crash for a long time, that is, the kind that will freeze the exchange. This situation will definitely happen again. The specific time is unknown. It is like the sword of Damocles, hanging over your head, you have to be on guard!
