2. Target transaction executes, causing an increase in price
3. Back-running transaction: Sell at a higher price after the target transaction is completed

Risk Factors:

• Failed transactions can result in losses for sandwich attack bots
• High gas fees may eat into their profits, especially during periods of network congestion
• Competition from other sandwich bots can make it challenging to consistently profit
• Potential regulatory scrutiny as authorities pay closer attention to such trading practices

3. Sniper Bots: The Precision Strikers

Sniper bots rely on technical analysis to identify optimal entry and exit points for their trades. They aim to execute trades with precision based on specific patterns or indicators.

Key Features:

• Integration of advanced technical analysis tools and indicators
• Real-time processing of market data to identify trading opportunities
• Automated identification of entry and exit points based on predefined criteria
