I have studied what happened to GOLD and SILVER markets to know Wall Street are 100x short on these assets so manipulating the price of these metals via derivatives/futures markets.
Bitcoin could fall to the same fate if we not careful.
Basically the market makers always win. They are the casino who enable the trading of these assets. Wall streets knows this game too well and how to win.
