Except weather has an element of predictability, at least over the short range, the realm of finance is highly unpredictable even in the short term. Who foresaw this crash?
I sold all my ETH at 297 right after it was starting (I make sure to check the markets before I sleep because China is often more market moving than the US/EU). I've been worried about the truth of the recent statements made in China about closures. This is obviously totally anecdotal and I made a really, really lucky call. Can't say I thought it would continue to go down this heavily. I consider any money I've put in these markets mostly play money anyways.
probably the PBOC, who will use it to 'buy the dip'
