At the current rates, I suppose most sales of AMBER are happening in "real" money.
AmberDev has hinted to this in previous posts.
This implies outside influence on dividends that will likely impact payouts for shares not purchased directly from AmberTrade.
Keep in mind, they can change the rules AT ANY TIME for investors not purchasing directly from AmberTrade.
10,000 coins?
They may decide the minimum balance required for dividend payouts should be 20,000.
Something like this will happen soon, the model of increasing available "stock" is unsustainable.
What the Crypto markets need is a trading mechanism that allows for "shorting" coins.
This may help to weed-out smaller valued coins, but, make it harder to start a "shit coin".
If you buy shares (also in Amber) you buy the part of the company. The capital of the company is 5 000 000 pounds. Each traditional share is worth 1 pound, each Amber - 0,05 pound. The company can send you the certificate of ownership.
