How Does the Time Taken to Execute the Attack Influence Its Success Rate?

The time taken is crucial. A successful 51% attack requires the attacker to maintain the majority hashrate long enough to secretly mine a longer chain that includes the double-spend.

The longer the attack takes, the higher the rental cost and the greater the chance of detection by the network or exchanges. Quick execution minimizes cost and the window for defensive measures, maximizing the success rate.
