As one example, when the CME launched BTC futures last year, the price crashed. It's all about timing.
price didn't crash after Futures launch. the price had gone up with a sharp rise before the launch in anticipation of positive news and then when the news came out itself it was time to take the profit out so the price dropped. it was more like a correction. and the the big bang happened to $20k.
Isn't that what he was referring to? Timing = sell the news = short the crap out of Bitcoin when CME (the largest exchange in the world) opens its markets.
If you also take into consideration that Bitcoin's worst months in terms of price action are all the first couple of months of each year, then it has only made people's urge to sell stronger. It applies to Q1 of 2019 as well, so what I'm doing is short Bitcoin around December 25 and buy back lower when most of the selling has been done. You can look it all up on the charts, they don't lie.
