1. Your service works like exchanges, which your users don't have access to the private keys.
2. With the free starter plan, your users can only get 2 receiving addresses.
Just my humble opinions.
1. Not like an exchange, we are BIP32 HD, meaning each user has a private key assign to them. Funds are never mixed and can be audited by the user at any time. There is a big feature you will like coming soon, stay tuned.
2. We offer a many more features (Onion, Funds forwarding, BIP32 HD, etc...) and quality support. We you are not selling customer's information to advertisers the natural source of revenue is monthly fees.
