imo, when you buy bitcoin, whales and traders are taking the other side of your bet and trading against you. this prevents any type of price manipulation from someone with deep pockets, so they can't "buy" the market. Example If some entity buys 10000 btc, whales and traders are not going to let them come in buy, pump the price because of the thin books, drive the price up and let them take profits. whales will sell and  drive the price down and make the buyer sweat it out and make them work for their profits(baghold). same goes for selling, you sell 10000 btc the price is going to most likely go up and not let you buy back at a lower price to immediately wash rinse repeat. so I look at bakkt in this way, if the price dumps tomorrow, this means people are buying, but the traders are trading against the new money. if price goes up that means there are people selling the news and whales are buying.
