I like how easy it was to set up our blockchain network using HashGraph! It's very user friendly (even if you're not familiar w/ crypto). The support team has been extremely helpful as well - they are always willing t o answer questions or help get things setup right away when we need them most!! There really isn't anything bad about this product so far -- everything seems great thusfar & highly recommended! We have an internal marketplace where users will be able purchase virtual items from one another through their own personal accounts via ethereum smart contracts built into swirlds' Blockchain Networking Platform called "Hash Graph".
