Position building suggestions

Selecting the appropriate price for building positions should consider market volatility based on current market prices and trends.

Current price: approximately $0.860552.

Historical low: approximately $0.431578 (showing significant price growth potential).

Suggested entry price: If the market continues to be bearish, consider gradually building positions in the range of $0.70 to $0.75.

Risk management: Set stop-loss levels, such as near the historical low of $0.50, to prevent further losses.

Market dynamics and risk assessment

Market sentiment: The current cryptocurrency fear and greed index is 79, indicating extreme greed in the market, which may lead to short-term price volatility.

Medium to long-term outlook: Given Arbitrum's leading position in Ethereum Layer 2 solutions, holding it for the medium to long term could yield substantial returns, but one must be cautious of rapid market changes.
