no one knows exactly (if the price goes to the moon - you will have lambos with 1k-5K ICNs)
just for the info you need to know if you hold 1 000 000 ICN you have only 1% of all available tokens...
My bet is you need to look at this way ( you need to know how much $ you can spend and you wont miss for a year) and then you will see how much money you get from DIVIDENDS and such!!!
my prediction is if you hold 1-10K you are small fish (in best case scenario you can buy a lambo(used one), but only 1)
30-50k ICN you are fish
100-300K ICN you are shark
500K + ICN you are whale
1Mil -10Mil you are big whale
