Here are two formulas to people that want to have dividends, you just sell the value you get of the formula and you still are holding the same %share of Iconomi.

a=b*(1-c/d)
a=b - (c *e)/100

a = Sell
b = Holding
c = NewSupply
d = OldSupply
e= %Share You Had Before


Examples:
You have 10,000 ICN now
Total Supply Now is 100,000,000 (https://coinmarketcap.com/assets/iconomi/)
With the burn let's say it went to 98,500,000
So, using the first formula:

a=b*(1-c/d)
a = 10000*(1-98500000/100000000)
a = 150 ICN's

So, Just sell 150 ICN's and there is your dividend without losing your old %share


OR

If you know how many is your %share you are holding now you can use the second formula.
Let's say you hold 0.01% (10,000 ICN now)
Using the second Formula:

a=b - (c *e)/100
a = 10000 - (98500000*0.01)/100
a = 150 ICN's

So, Just sell 150 ICN's and there is your dividend and still holding 0.01% of Iconomi
