Hey together,
this whole thing sounds interesting. Is there any explaination about how to use it in detail?
Do i get the Devidend based on what i payed on SAE? or what?
Sorry for the newbee questions

I would be happy to explain. Yes the dividend is based on your total investment. So if you bought 10,000 NXT worth and the dividend was 4.5 for the week 450 would automatically deposit into your account. The transactions can be done through the NXT client or a web-based client like Secure Asset Exchange. If you wish to cash in your dividends you can always click on the "Send NXT" button and send them to your favorite exchange where NXT is traded against BTC.
It is actually very simple once you have done it a few times.
If you have any other questions feel free to ask! I am happy to help.
SO if I buy, for example right now at SAE:
100 AutoDiv @ 6.21
and
100 AutoDiv @ 6.38
I invested: 1259 NXT
Next devidend: what do i get?
200 AutoDiv*4.5 = 9 AutoDiv
At which rate will they be converted?
