Thank you for your feedback.
The analytics software we leverage is open source and of course anyone can get it themselves. However, the server infrastructure, integrations, maintenance and whole host of other things are not. We are offering this service to those who can't or don't want to spend the time getting something like this up and running for themselves/friends/others. We have no intention of misleading users into a paid service which is why we offer a 1 month free trial and a generous refund policy. If you can't see yourself benefiting from the service, no worries. But if you are, we hope you understand why we are subscription based.
Also from what we have seen, there is no tool out there that allows for custom SQL scripting for crypto currency analytics. For most I imagine this feature wouldn't be of interest but for data scientists, it's immensely powerful. We invite anyone to try for themselves!
