I like how easy it was for me as an individual developer, or even someone who has never touched code before in their life to set up my own private chain! The documentation could be better - but that's just nitpicking at this point! If you want your project to have its own blockchains (and not rely solely upon Ethereum), look no further than multichain! We are using multichains to solve our business problems of having multiple parties involved within different industries creating decentralized systems without needing too much trust between them.
