CLARIFICATION: Leocoin in my opinion is scammy. I wouldn't put money in it and would advise other likewise.
This is a theoretical post only - it is NOT an endorsement of Leocoin or MLM.
EDITED POST:
MLM tends to be a bit pseudo religious and cult like - I don't personally like it - but it is legal in most countries.
The main exchange, the code, the mining (POS) and the promotion is all controlled by the same people and main stakeholders.
Centralisation makes it risky. If the system collapses it has no recoverable value.
With MLM you always pay a high premium for a product because it has many levels of commissions to pay - so you will never get a bargain or good deal. So it does NOT make a good investment.
There are some successful MLM products - like Avon, Herbalife and Amway - however this is not necessarily a good thing. Just because companies that use questionable sale techniques don't go broke doesn't make them worthwhile joining.
The price of LEOcoin is being manipulated on the exchanges.
This images shows that exchange pumps take place to give the appearance of market change. It is just a price increase instigated by a large holder of the Leocoin crypto.
Because crypto is largely unregulated many unethical things can occur. If this happened with a registered security in a regulated market it would in most likelyhood result in prosecution.
This is something that happens in crypto and should be viewed as a warning of market manipulation.
HOWEVER - AS A SYSTEM:
CONTROLLED MINING, CONTROLLED EXCHANGE, NODE CONTROL and SOFTWARE CONTROL can have advantages and makes a system secure if the people controlling the system stay around. It also makes you totally dependent on that group of people.
Controlled POW mining (rather than pos), controlled exchange, node control and software control would be ideal for an existing trusted and regulated bank. It would make transactions easy and secure. Government oversight and strict financial controls would be needed for such a system to be safe.
If it was run by a established bank and had some government oversight it would have commerce benefits.
Without such a trusted organisation and government oversight it creates additional risk.
Crypto is still largely unregulated - unlike financial markets. Centralized control creates extra risk.
So when security, anonymity, price and success of the coin is controlled by the same group of private people it becomes like joining bartercard or investing in interest bearing gift cards or sending via paypal.
It does remove a lot of the benefits of decentralized open source crypto that is subject to market forces and relatively free from government control.
NOTE: This post is heavily edited from the first post to make it clear that it is only talking about SYSTEMS.
This is NOT AN ENDORSEMENT of Leocoin. In my opinion Leocoin is NOT a good investment.
In my opinion Leocoin has been sold using exaggerations and misrepresentations.
