Matrixport analyst Markus Thielen has highlighted the increasing need for risk management in Ethereum investments as the cryptocurrency's price fluctuations align with the weekly Stochastics indicator. Thielen warns of heightened caution at current high levels. The Treasury remains the primary buyer of Ethereum, but its purchasing capacity may be constrained by the asset's declining value. Investors are advised to bolster risk management strategies in response to market volatility and the risks linked to leveraged long positions.
