Peanuts, really.
Iconomi must make hundreds of millions of dollars before ICN dividends can be anything more than $0.01 per ICN per year.
You can make more money from Dividends in a traditional savings bank account, than by holding ICN.
Publicly-known ICONOMI.performance holdings:
5M GNT: ($151.8k current value) - ($51.3 invested) = $100.5k unrealized profit
4222 GBYTE: ($385.2k current value) - ($0 invested) = $385.2k unrealized profit
Total unrealized profit = $485.7k
Estimated unrealized dividends for ICN holders: ($485.7k)×0.20 = $97.1k
*20% performance fee is just an estimate, not officially announced yet
For people who bought in at ico price of $0.13, that would already be a 0.75% return if dividends were realized.
That's from investing just 1% of ICNP's seed money. The main source of dividends, the platform, hasn't even launched yet.
Average yearly return of a traditional savings bank account in US is 0.06%. If you account for inflation, then it is negative 1% or 2%
The effect on the market and the ROI from your trolling is less than peanuts.
