ok fair enough---but that all boils down to investor demand. the actual cost doesn't matter---only the perceptual effect on buying/selling pressure. there is a flip side to that: if the market holds below the perceived "price where miners will prop the market" then that could reinforce fear and increase sell pressure. i could easily see price crashing to the $2000s or $3000s, miner costs be damned.

all that is to say, there is no magical bottom like franky1's $5800. there is only supply and demand. and the lower we go towards miner's true pain points, the more likely they will capitulate at high volumes far, far below $5800 or any other magic number.

in the same sense, the news from goldman sachs didn't actually do anything. at most, it just helped trigger a down move that was already going to happen eventually. the reason a selloff like that occurs is because people are ready to sell; sentiment is negative and the market is bearish.

last year during the bull run, nobody would give a shit what goldman sachs was doing. it would have been an afterthought. it's only because the market dropped $1000+ in a day or two that people are searching for a cause, after the fact. "oh, it must have been the goldman sachs news!" no, i doubt it!
