Firstly, you cannot use exchanges to receive icns.
If you use some wallet such as myetherwallet. You can receive dividends in that Wallet in ETHs. Also if you decide to keep them in iconomi itself, you'll still receive dividends. Most probably, you would get dividends in a eth online Wallet by iconomi.
Thanks I know all of that, maybe my question wasn't phrased right. Will exchanges themselves (eg. Polo, Bittrex, ...) get dividends from ICN tokens they hold from investors?
I'm sorry.
That's a nice question. I would request devs to throw light on this.
However, we would be receiving weekly dividends.
Suppose we would receive dividends on Sunday at some particular time. Exchanges hold the currencies generally for short period time. So think about that the given icns receive dividends at that moment when they are on exchange.
Anyhow, this could happen,. And if trade volumes are high there are chances that exchanges receive the dividends.
In my opinion, exchanges can receive dividends. As it would be very difficult for Iconomi to check whether the icns are with a person or exchange.
