BitClassic was a Bitcoin wallet that use to save also other altcoins and was considered as a simple but good cryptocurrency wallet. However, during a lot of time the company left the world of the internet without making notable what happened to the project, and the users who already joined it and opened an account. The platform is now closed, it does not grant access to everyone without matter the time zone.
There exist many interested and curious researchers that are always looking for something to make it more clear, but all information is limited. An in the case of this product, there does not exist anything. The team, developers, and the CEO themselves are part of a cam by creating and delivering a project like this, that just a couple of years later disappeared. There might have had many users affected when downloading the wallet.
There are pic information, data of users, contact with developers, or social media available. All vanished as far as possible. And the project is now another abandoned source that has touched slightly the reputation of some other storage services for cryptocurrencies.
All that I can say to keep users, at least, safe is that the project was totally canceled, and there is no way of entering any of the services. So, users can keep away from risks, issues, or simple curiosity.
