The way you pointed this out was exactly the way I was thinking - the thin line between investment and scam has been deliberately blurred.
Yobit have capitalised on this scam and is paving the way for other exchanges to do the same. Before they would scam and close but now exchanges can offer useless and worthless tokens which cannot be used or transferred then cite market conditions for their collapse all the while they pocket the hundreds of thousands if not millions of US$.
Already exchanges are launching their own fake IEOs or colluding with scammers and heavily promoting them to their users then pocketing the cash while investors and users watch the value of their investment plummet. This investbox scam from Yobit is a modification on that theft but a with few modifications.
It is clear, Yobit know exactly what they are doing by pulling off this scam and using as much protection they can get from a legal perspective citing "technicalities" as they can in an attempt to pre-empt any legal proceedings which might take place in future.
What is ironic is that Yobit are hiding behind anonymity, their website has absolutely zero details about who owns and operates them and their Terms/Conditions are pointless and all this was done in the hope
potential future lawsuits might be put-off for as long as possible.
How is it possible that the tokens have nothing of value yet are a number plucked out of the air effectively and added to user balance accounts yet users sadly fall for the scam? No blockchain, no trading mechanism outside the website and no material or monetary value... very sad indeed to see a modern day scam on this scam that generated over 68 BTC that was mentioned earlier.
We all have to wait until a victim accepts they were scammed then steps forward to post here with their claim - then see which way it all plays out.
The whole thing is actually set up quite intelligently to let them defend against accusations.
It's not actually a Ponzi because YoBit aren't paying out later investors using earlier deposits, because they aren't paying out anything at all. They sell the initial x number of tokens, and all later trades are between users, with early buyers selling directly to later ones. The "interest" paid is created out of thin air, because there is no blockchain or smart contract rules to abide by.
They can claim the deposits to InvestBox are 100% safe, which again, is technically not a lie. A user has to trade BTC for X10 first. Only once they own X10 can they deposit it to the InvestBox. Their X10 token is completely safe and can't be stolen since it doesn't exist, will earn 10% interest which they can create at will, and can be withdrawn to their trading wallet at any time.
The massive loss in value that all "investors" will see can be chalked up to poor market conditions - "It's not our fault if no one wants to buy our completely made up non-token".
Now, obviously anyone with a little sense can see through all this, but people with sense aren't the ones using this "InvestBox". The question is have they actually broken a written contract anywhere?
