First, there was no speculation in the example, that Ruja says you will get over 2 million OneCoins with 118 000 euros Ultimate package. it is in the video. Absolutely no speculation there. It is also not speculation that Ruja decides the coin value, which is 6.95€ at this moment. So there is zero speculation, that Ruja is selling a package with 118 000 euros, which she implies is worth over 13.9 million euros even without any coin price increase.

It is very important to notice this incredible return of investment, even with the exact same coin price. Infact, even if the coin value goes down to only 1 euro, you would still make a huge profit with the over 2 million OneCoins you get with the 118 000 euro Ultimate package, still over 2 million euros, even if OneCoin value was only 1 euro! And there is zero speculation here. Straight from Ruja's mouth, and the coin value from the company page. With less valuable packages it is the same situation but in smaller scale. For any sane person this should totally ring your alarm bells.

Or how many real cryptocurrencies you know that still gives you over 16 times profit, if the value of the coin drops to 1/7 of the value when you invested (6.95€ -> 1€)? This is what the Ultimate package currently "makes possible" (of course not in reality). This should prove to even your granny, that there are a lot of things wrong here. And this is zero speculation, from the video by Ruja: "this package (118 000 euro Ultimate) will generate over 2 million OneCoins".

Do you know how market-cap of a cryptocurrency is calculated?
Market-cap: amount of coins * coin value. And this is exactly what OneCoin does, and claims it is the market-cap of the whole company as well. They don't say their market-cap is based on sales of the packages, so you are wrong claiming that. They don't give out any financial figures of the company anyway.
You can go to xcoinx.com (OneCoin's fake cryptocurrency exchange page) and calculate: amount of coins * value of a coin. There you get the market-cap which OneCoin claims it has as a company, and which Ruja pulls out of her handbag.

Also, regardless of the centralized blockchain, they could open the OneCoin trading for all, and let the market decide the coin price. But this is of course "in the future".

Ruja herself says that she doesn't expect the coin price to go down, she expects it to only go up. Of course, because she herself decides it (which is totally ridiculous).
Even the doubling of everybody's coins, and changing the max coins to 120 billion won't bring the coin value down, but Ruja says coin price is expected to grow (surprise surprise). All this is against all known laws of finance.
I'm sorry if this is not enough evidence, I don't know what is.

Here is the video, at position 9:07 Ruja says "I believe that all these changes are actually for our best, and will grow the value of the coin significantly."

It is basic financial knowledge, that if you flood "the market", the price will go down. First, everybody's coins are instantly doubled 1st of October, and then OneCoins will be "mined" a lot (10 times) faster, but Ruja says coin price just goes up. This is also very clear sign of a scam, and ponzi scheme.

The following is speculation, but very likely scenario because Ruja is saying the coin value only goes up:
After 1st of October OneCoin's fake market-cap will grow over 3 billion euros per month (assuming coin value stays at 6.95€), because Ruja won't allow the coin price to drop and 10000 coins will be mined every minute (instead of every 10 minutes currently). 10000 coins per minute mining speed is confirmed by a known OneCoin promoter, Ken Labine.

So after 1st Oct, 14.4 million coins will be generated every day, instead of the current 1.4 million coins a day, but of course the coin price will stay the same or increasing ( this is what Ruja says in the video above). This should ring an alarm bell very strongly, but many onecoiners are just too greedy to realize anything strange here. Very soon after that onecoiners will be celebrating that OneCoin over takes Bitcoin in market-cap value, which is totally ridiculous claim cause there is no public market which decides the value, only Ruja.

There can't be really much more clearer evidence, until police finds it from OneCoin's servers. But I can make follow up post which further shows that this is not a company to be trusted at all.
