Participating in short-term trading in the cryptocurrency market does have the potential for high risk and high returns. Before considering trading, make sure you understand the volatility and potential risks of the market. Here are some common, high-risk but potentially high-return coins for reference: 1. **Small-cap coins**: Small-cap coins are usually extremely volatile and have high investment return potential, but they also have high risks. 2. **DeFi project tokens**: Decentralized finance (DeFi) project tokens often experience wild fluctuations in the market. Some new projects may have high returns, but they may also face risks due to lack of liquidity. 3. **NFT-related tokens**: Some projects and tokens related to non-fungible tokens (NFTs) are popular in the market and may rise sharply in the short term. 4. **Emerging projects and ICOs**: Participating in the initial coin offering (ICO) of emerging projects may bring high returns in the short term, but be wary of bubbles and scams. It is recommended to do sufficient research before investing and only trade with funds that can afford to lose. At the same time, you can consider setting stop-loss orders to reduce potential losses. Stay calm and don't blindly follow market hotspots. It is very important to invest rationally.
