Trump's "swamp" is a term he uses to describe what he considers corruption and bureaucracy in Washington, D.C. and the U.S. federal government.
If the "swamp" is likened to a phenomenon in the cryptocurrency world, it can be understood as widespread corruption, opacity, and manipulation in the cryptocurrency market, including but not limited to rat trading. For example, the "swamp" in the cryptocurrency world can include:
1. **Insider trading**: Similar to rat trading, trading with undisclosed information.
2. **Market manipulation**: Manipulating the price of a currency by means of pumping and dumping.
3. **Ponzi scheme**: The money of new investors is used to pay the earnings of old investors, and eventually collapses.
4. **False information**: Misleading investors by publishing false information and exaggerating the prospects of the project.
5. **Conflict of interest**: Some project parties or exchanges use investor funds for personal gain.
