Why Is a 51% Attack More Economically Feasible on Smaller, Less Popular Cryptocurrencies?

A 51% attack is more feasible on smaller cryptocurrencies because the total hash rate securing the network is much lower. This means an attacker needs to acquire significantly less computing power to gain a majority.

The cost to rent or purchase the necessary hash rate is often low compared to the potential profit from a successful double-spend, making the attack economically viable.
