This is wrong in so many ways!
Also one could appreciate the fact that steeminc derives some add-revenue from such clients, money does not justify all action. There has to be a red line and someone claiming:
AMFEIX claim that previous performance suggests a return of between 10% and 20% per month on your investment
stepped clearly several yards over it.

Everybody that has some trading or investment experience knows that monthly returns of 10% to 20% are impossible to achieve and even if you judge that this is neither a forecast or promise, its clearly the picture amfeix wants to put in your head.
And I am sure you gentlemen know, that this is not possible, too.

So what will you do?
Either you seriously try do do it with trading, long and short (/cash) - based on whatever trading strategy - and you actually believe you have a coin flipping winning streak of 100 tosses heads straight.. then you might be able to show this 10 to 20% monthly return for a full year

or you simply go long any coin and pray that it will double or quadruple over the next month and then the investor gets 80% of the 100% he would have had if he invested directly into the coins.
Both has no value at all for anybody "investing" into your "fund".

How could you have done it in a way that doesn't cross the red line?
Explain your strategy and trading pattern, and then explain why you believe you have an edge over all the other traders. (it could be that you actually have an edge over other traders because of x,y,z..)

But then again you should not point to 10 or 20% monthly returns..
.. you could claim that your overall performance .. due to your edge.. should systematically outperform a basket of crypto currencies or bitcoin...
...these would be by far bold enough claims!

And to anybody here asking not to downvote amfeix post: if not this post, which post should be downvoted at all? Yes.. I get your good intention.. but the first steemians loosing their money in this "fund" instead of purchasing steem and leaving this community will already be enough to render the advertisement money worthless.. not speaking of enraged "investors" calling he SEC and steeminc and the steem community having to bear the consequences...

I doubt that it was a clever decision of steeminc to have a business relationship with amfeix but OK.. this is the blockchain.. its free and self regulating.. hence downvotes and critical feedback are in this case very much justified and necessary...
