Why Are Smaller, Newer Proof-of-Work Cryptocurrencies More Vulnerable to a 51% Attack?

Smaller, newer PoW cryptocurrencies have a significantly lower total network hash rate compared to established coins. This means the cost for an attacker to rent or acquire 51% of the hash power is much lower, often achievable with readily available hash rental services.

The lower security budget makes the attack economically feasible, making them prime targets for malicious actors.
