It's nothing to do with the BCH fork, or BAKKT, or the ghost of Satoshi.
Watch the news. Stocks and shares are tumbling as well. US and China worries are affecting the stock market, and the same people selling there are selling here. What is the point of being decentralised if "big money" still owns your ass? It's a joke. Crypto is just another column on a "profit & loss" spreadsheet somewhere.
My prediction? Back to $600, the price before the last big pump. That will wipe out most ICOs and AltCoins as they will be worth absolutely nothing. You can also say goodbye to most of the big money investments in trading platforms and exchanges.
First of all in order to drop the price of bitcoin the only way is to sell bitcoin, which means by your logic the "big money" needs to own a lot of bitcoin and drop the price of it. Let's assume there are a lot of whales who own a lot of bitcoins that keep on selling, why do you think they would wait in between so much ?
I mean when the price went from 6.5 thousand to 5.6 thousand I would totally understand the logic but than it stayed there for a while and dropped to 4.8 thousand and so forth for a while until it reached to 3.4 thousand now.
I really doubt bitcoin is "controlled" by some big whales but Craig Wright is literally the only person with that much bitcoin which means "bitcoin cash" that you disregard is biggest reason we have for this price. Not that many "real money" is in bitcoin, most of it is people who got in early.
