The purpose of these Alternate Cryptocurrencies varies on why they are made on the first place. However, some of these Cryptocurrencies have never even reached their original goals because of the lack of further development and lack of attention that they have been expecting to get. These Alternate Cryptocurrencies are something that everybody can create as long as they have the knowledge to develop it and maybe some developers do it for the money so as long as they are creating new ones, they can create a source of different income for them and maybe that is one point if you are a developer.
