Whenever I try to do a search on why different algorithms are used for various coins I am having a tough time coming to any substantial conclusions. It seems apparent that there are a few coins or projects that are steadfast in their Anti-ASIC stance, so this would be an explanation for a minority of the market. What are the benefits or faults of each algorithm and what makes the developers of a coin decide upon a particular algorithm for the protocol to operate with? It seems frivolous, please help me understand.
