According to Cas Abbé, traders should avoid chasing price pumps with full position sizes and must pay close attention to the current market structures of Bitcoin (BTC) and Ethereum (ETH) before entering trades. Abbé stresses the importance of maintaining strict risk management even during periods of high altcoin volatility, often referred to as 'altseason.' Additionally, traders are advised not to follow trade calls from others without proper confirmation, as this can lead to unnecessary losses. These trading guidelines are crucial for minimizing risk and optimizing returns in today's volatile crypto market (source: Cas Abbé).
