Which algorithm is most profitable NiceHash?

Right now, DaggerHashimoto (aka, Ethash, what Ethereum uses — a modified variant of DaggerHashimoto) tends to be the most profitable, though sometimes Octopus, Kawpow, or some other algorithm might climb to the top.

What is a mining algorithm?

A mining algorithm is the set of rules and mathematical operations used by miners on the hashing process of Proof of Work cryptocurrencies. In order to achieve this, the miner continuously tries random nonces (number only used once) on the hash function in hopes of finding a valid solution.

What is NiceHash & how does it work?

What is NiceHash and how does it work? NiceHash is the largest hash power broker marketplace that connects sellers or miners of hash power with buyers of hash power. Hash power is a computational resource that describes the power that your computer or hardware uses to run and solve different cryptocurrency Proof-of-Work hashing algorithms.

Is it possible to compare hashrates between different mining algorithms?

Comparing hashrates between different mining algorithms or using the same overclock settings is generally not feasible. Each mining algorithm has its own set of mathematical operations, which require different amounts of computational power and memory to solve.
