It is fine if you take a chance by yourself. You can do with your own money what ever you want. However, considering that what I have said above is just a really small fraction of what there really is wrong and shady about OneCoin (there really is enough material for a book), I don't think it is morally right to market this scam as an MLM salesman to other people, who maybe don't have knowledge and understanding of what they are getting into, and trying to get other people to join your OneCoin downline. I think that is absolutely morally wrong.
Yesterday OneCoin lost again their bank account, which was their Deutsche Bank account in Germany. And they have to find a new bank from Europe, again. It is getting more and more difficult all the time, because OneCoin has a very bad reputation. The explanation will probably be, that banks are afraid of OneCoin, or something bulls*** like that. Last time a couple of months ago when they had to change a bank, the explanation was that they needed a bigger bank because OneCoin is growing so fast, but that card has now been played already.
They have been changing banks probably more often than drug cartels.. :D I have lost count how many bank changes there has been already.
