I've been baffled as to what caused the stall in this textbook breakout. After some digging, I initially just put it down to the DXY having a solid drop, but as DXY continued to fall, neither BTC nor ETH continued to climb - which was odd. I moved past it, putting it down to a lag in liquid exchange.
While scrolling through Twitter, I found some information that could help explain the stall further.
See, there was a recent hack that occurred on the platform FTX. An API traders could use to link external accounts was not secure. This was detailed to the platform managers some days before the hack - FTX ignored the call to action. Some days later, people took to Twitter complaining that they had lost large sums of money. FTX failed to respond publically and to the individuals complaining about the lost funds (many even had evidence of activity on their account that they themselves were not transacting). 150m was lost to the exploit.
As many do with situations like this, they run in fear of being impacted too. As such, a heavy liquidation on the FTX platform has taken place. This likely explains the quick leap up into a stall for BTC and ETH. To be clear, 1.2B in currency (almost 80% of FTX's holdings) was liquidated and moved off FTX. This means the rally we have experienced is an exhaustion rally from the liquidation of currency off of FTX. It likely is an unsustainable rally, and therefore a move down maybe coming.
