Proof-of-work-Let's give the money to the jerk who wastes the most resources and destroys the planet.

Proof-of-stake-Let's give the money willy nilly because distributing a new coin fairly is not important. In other words, let's scam people and give all the money to ourselves.

ICO-Let's scam people.

Useful proof-of-work-Let's give the money to the person who solves a useful problem. This will create a valuable cryptocurrency.
