After falling below $29,000 on Monday for the first time in a month, Bitcoin (BTC) traded at $29,100 on early Tuesday. The bearish price action comes ahead of an expected 25 basis point increase in interest rates by the Federal Reserve on Wednesday afternoon. With investors fully anticipating the move, Mike Schwitalla, Head of Trading at Crypto Finance AG, will be watching to see if market participants take the actual decision like a hawk. Should there be a slight sell-off in risk markets, it is looking at support zones for Bitcoin around $28,000, $26,000 and $25,000.
