Arbitrators are those who try to buy something cheaper somewhere and sell for a more expensive price; they are now working very actively. In fact, they need to control Multitoken balance. Exchanges, in turn, occur constantly, depending on the parameters set.

Daily trading exchanges limit will be set while you create your MultiToken. You can choose between two options - certain percent of token price or fixed amount depending on the type of rebalancing chosen. All the exchanges done through this MultiToken will lie in those limits. MultiTokens which will include MTK tokens will be involved in the exchanges more often than without it. This feature is still to be determined and some details much change in the future.

Multitoken is not the same as MTK . Multitoken is a portfolio of tokens, and MTK is a token to be released. Holders of MTK token get exchange fees by holding MTK on MultiToken.
Amount of MTK token inside multitoken defines probability this multitokens to be chosen as an exchange for concrete trade operation.

That means, Multi Token will be the platform for another new cryptocurrency isn't it?
And about the difficulty level of creating a project, so is it complicated process or it's just a simple process.

This project will let a group of people be quicker, sharper than the rest of the market.   That's why I consider it to be disrupting. At least for the people like me.  

I've got this strong feeling this project will be disruptive   

I wouldn't trust this website 

So as far as I understand you are going to release two different types of tokens. What's the main difference between it?

it seems to me possible to take the strategy of any fund that buys top coins.

I want to see the test results as soon as possible. It is also possible to somehow compare them with existing funds and their strategies. Is this possible?
