Is Onecoin a Scam Or a Really Coin? What do you think?

In their oficcial page say OneCoin empowers millions of people by providing borderless, low-cost financial transactions and connecting them to the financial world. OneCoin has developed a loyal, global customer base of millions of people in over 195 countries and six continents and is independent of governments

As cryptocurrency lacks several fundamental properties, is a "currency" of a company means that is centralized and controlled by the company. It is not open source. They require an "investment" minimum of € 100 and is filled with inaccuracies and false promises.

The cryptocurrency concept.

Is a medium of exchange like normal currencies, but designed for the purpose of exchanging digital information through a process made possible by certain principles of cryptography. Cryptography is used to secure the transactions and to control the creation of new coins.

Cryptocurrency most popular features:

• Decentralized (not dependent on a company or government)
• The market value is generated by its use
• They are open systems.

In my opinion Onecoin is a scam (ponzi scheme) for the following reasons:

• The currency is in control of a centralized company.
• Currently the market is completely closed onecoin
• No projects recognized for use in the future.
• The money given to members comes from new entrants.
