OneCoin is 100% scam. There are many proofs, but I present here one:

You can buy the new Ultimate package with 118 000 euros. Ruja says that it will generate over 2 million OneCoins:
OneCoin price is not decided by public market, rather the company decides the coin value. At the moment the coin value is 6.95€. So, with 118 000 euro Ultimate package, you will get according to Ruja, over 2000 000 onecoins *6.95€= over 13.9 million euros, just like that. This doesn't need any coin price increase or anyting. Just investing 118 000 euros will according to Ruja generate over 13.9 million euro worth of OneCoins , 117 times the amount of Ultimate package price. All this with the current 6.95€ coin price.

But there are even wilders figures from onecoinfo.com:

With the combo package Tycoon+Premium+Ultimate, you pay 139 280 euros, and it generates about 2.4 million OneCoins, which in euros is 2.4*6,95€= 16.6 million euros.

This "small" 119 times value increase with the SAME coin price is just the start. The fun part is the coin price increase predictions..
With 100€ coin price, the investment value is already 2.4*100€=240 million euros as you can see from the chart.
The coin value increase in this calculation is about 14-16 times, but the investment value increase is way over 1700 times!! How is that possible? The answer is simple - it is not possible.

Also, couple of days ago the fake market-cap of OneCoin increased about half a billion euros in 1 second, when Ruja decided to raise the coin price from 6.25€ -> 6.95€. The market-cap of OneCoin is totally fake, because it is not based on public market. 1st of Oct Ruja will double everybody's OneCoins, but the coin value is expected not to drop, but just continue to grow. OneCoin will change the blockchain and increase maximum coins to 120 billion, and they will generate for everybody double the amount of their current coins. This should also instantly double the fake market-cap.

OneCoin will also start producing coins with increased speed. According to Ken Labine 10000 coins every 1 minute, instead of every 10 minutes (currently). So after 1 of October they will produce 14.4 million coins a day and around 438 million coins per month. Per month with the current 6.95€ coin price, that is over 3 billion euros worth of OneCoins in a month, and way over 36.5 billion euros in a year (in fact much more because the coin price will only increase) which is simply said ridiculous.

There are so many things which show OneCoin is a scam, that there would be enough material for a book already. But the point is, that it looks like you have a lot of wealth on your OneCoin account, but due to selling restrictions, it is pretty much impossible to transfer the OneCoins to euros, and you can't buy anything with your OneCoins either.

And because of the above things, and many many other reasons, like a very bad reputation, it is extremely unlikely that we will see any serious merchants supporting OneCoin, even if you could transfer your coins to a merchant. At the moment the coin transfer is not even possible, other than between your multi-level-marketing down/up -line..

There is absolutely no doubt. OneCoin is a scam.
