Bitcoin's Price Volatility Continues Ahead of Fed Interest Rate Announcement.

Bitcoin's price has been fluctuating around $28,000 as investors await the U.S. Federal Reserve's interest rate decision on Wednesday. The recent announcement that the Fed would increase the frequency of dollar swap lines with major central banks has calmed exchange volatility and contributed to the rise in risk assets, including bitcoin. The threat of a global banking meltdown has also diminished, and investor hopes are mounting for a more dovish Fed policy. Bitcoin is seen as a hedge against the banking system, and its potential sustainability is difficult to determine. The FOMC's announcement will likely determine bitcoin's path forward.
