One of the biggest red flags signaling the Bitcoin bubble was about to burst came when JPMorgan's Jamie Dimon flipped bullish earlier this year, after years of urging investors to stay away and calling it a giant fraud. The reality is these Wall Street banks probably bought billions worth of BTC early on but needed more time to accumulate. At the peak, when they need exit liquidity, they promote it to their customers and push crazy price targets to get people to buy in. Wall Street is sleazy, and anything they say should be taken as a cue to expect the opposite, especially when it comes to crypto.(Jacob King)
