What I do know:

In the past 4 weeks OneCoin membership. Has gone from 5,000 to >50,000.
Membership in the USA is limited, if nearly nonexistent.
It is an MLM model, and money is being made on the MLM activity of OneCoin.
Cost of membership is from 130 Euros to 5,000 Euros.
130 Euro package awards 1,000 tokens, 5,000 Euro package awards 60,000 tokens.
Tokens are valued at 0.115 Euros.
There has been one token split 2 weeks ago.
Mining began January 20, 2015.
As of today, 220,000 coins have been mined.
(Edit Jan 28 - 550,000 coins mined. Seems mining is rather rapid...)
OneCoin is closed source.
OneCoin is not on an exchange.
I believe mining ease is 1 coin/ 5 tokens.
I believe OneCoin is based out of Bulgaria.
I believe Nigel Allen, a principal in OneCoin, has a shady past, along with some other principal players.

What I don't know:

Is this considered pre-mining?
What does it mean in general as far as legitimacy etc if this is pre-mining?
How can tokens be assigned a value if it is not public or on an exchange?
Once OneCoin does go public, can it be viable as a bitcoin cryptocurrency?

I have also found out that OneCoin has a new policy that in the event of another token split, they will apply the split retroactively. In other words, even if you have used all your tokens for mining already, your previous tokens will be doubled and automatically added into your account. Sounds wrong to me...

Over all question: Is OneCoin a scamcoin?
