I don't understand why everyone goes into a panic whenever BTC goes down?
most of the things you read on bitcointalk is not "panic" it is instead people FUDing to pretend there is panic and create panic in others while they buy...
Do you guys think there is a correlation between the sudden pump above $6K and the miners? Since some people claim that bitcoin at this moment costs $6k to produce. Therefore miners could be pumping up the price to be in profit again.
there may be a correlation but not the way you said it. miners didn't pump anything. it is all about what people were expecting to happen.
for example as you said people expected the "mining cost" to be X and expected it not to go lower than that X, so when it went below that price, it acted as a buy signal for them so they started buying effectively increasing the price back up.
