The cryptocurrencies with RSI indicators entering overbought or oversold zones on the 30-minute K-line are worth paying attention to. $LIGHT, $LAB, $GPS, $UNI, $ACT, $ZEREBRO, $B2, $ZORA, $AKE, $IO, $PLUME, $FLOCK, $PROM, $D, $UB, $DYM, $API3, $JST all show relevant signals. RSI overbought indicates that selling pressure may increase, while oversold suggests the possibility of a rebound. However, indicators are just a reference; it is also necessary to consider trading volume, support levels, and other factors for comprehensive analysis. Remember: technical analysis is only part of the picture, and risk management always comes first.
