A sequence of macro warnings coming out of the Goldman Sachs camp puts Bitcoin (BTC) at a risk of crashing to $12,000.Bitcoin in "bottom phase?"A team of Goldman Sachs economists led by Jan Hatzius raised their prediction for the speed of Federal Reserve benchmark rate hikes. They noted that the U.S. central bank would increase rates by 0.75% in September and 0.5% in November, up from their previous forecast of 0.5% and 0.25%, respectively.Fed's rate-hike path has played a key role in determining Bitcoin's price trends in 2022. The period of higher lending rates — from near zero to the 2.25-2.5% range now — has prompted investors to rotate out of riskier assets and seek shelter in safer alternatives like cash.Bitcoin has dropped by almost 60% year-to-date and is now wobbling around its psychological support of $20,000. Some analysts, including a pseudonymous trader Doctor Profit, believe BTC's price has entered the bottom phase at current levels.
