In the recent weeks there has been a resurgence of news about OneCoin, what appears to be a high-profile MLM ponzi scheme disguised as an altcoin. From what I can gather, the renewed popularity of the topic was sparked by OneCoin's Coin Rush Global Event.
Coin Rush Global Event
Watching this video as someone that has been around Bitcoin for 5 years now, there are more red flags here than you would see during International Workers' Day in some places. In fact, the video and OneCoin in general are such a good example of how you can bamboozle people by saying just the right thing that it might be a worthwhile exercise to dissect a lot of it.
The Basics
Going onto a cryptocurrency website you want to look for a few key pieces of information:
Who is developing the project / the code? You want to find at least a competent development team identifying themselves. Examples: Bitcoin, Ethereum, Ripple. For OneCoin, the best resource I could come across was OneDream Team's "Top Leaders", which only boasts some news.
Where is the company located? It is especially important for exchanges and other companies you're giving money to, but can be useful for the core development team if applicable. Examples: Ethereum (listed on the bottom page), Bitcoin Foundation, BitStamp, not as much for Bitcoin Core (as it's a more decentralised development) Ripple, OneCoin or xcoinx.
Where is the source code? If you can't see the code, you can't be sure what you're installing isn't malware or whether the blockchain itself is really there. Examples: Bitcoin, Ethereum, Ripple, but nothing for OneCoin.
Is there a block explorer? If you can't browse the blockchain data and validate it yourself, how can you be sure everything adds up? Examples: Bitcoin, Ethereum, Ripple lacks a proper explorer, but has a public API endpoint. For OneCoin, best you can get is a falsi explorer (thank you /u/TimTayshun for the screenshot)
Do any reputable exchanges trade it? A coin that isn't tradeable might not be a currency at all, but instead some "funny money". For a smorgasbord of examples, you can check out CoinMarketCap, indexing things as low as $8 market cap for COIN. OneCoin, despite boasting 5.2B USD market cap, is conspicuously missing...
Getting all five of the above points is a good start for any currency, but as we can see, even some of the largest coins are missing one or two of those features. Lacking all five does not bode well.
That's not how blockchain works
Putting all of that aside, let's look at the video proper and see what the event is about. Apparently the big news that day was that OneCoin is retiring it's old blockchain (!) and launching a new one in October so they can make more onecoins (!!). The justification being, and I kid you not, that they need more coins to grow, since there might not be enough coins for new merchants, Latin America, India, etc.
Let that sink in for a bit. A cryptocurrency that is not explicitly tied to a fiat currency is running out of coins for people. So instead of letting free market organically settle on a price it thinks the coins are worth and say, buying the coins from the market to give to the new merchants if they want, they instead decide to make more coins...
