I'd probably buy more considering they just burned another 742,000 thousand ICN tokens. So with every year they'll burn 2.5 million ICN tokens approximately. So 10 years from now, they'll be down to 75 million ICN tokens if my math is right and it remains at its current burn rate (more or less). 20 years from now, they'll be down to 50 million ICN tokens, and then their BTC value just keeps going up and up.
Sounds like a good deal long term or no? We have to think about it really long term. If you can wait 20, 30 years, this could be worth quite a bit for each ICN token.
Now, that's the rosy scenario. What is the worst case scenario?
But, the thing is there is no real usage of ICN for now. It doesn't matter if there are 1 million ICN remaining or 1 billion ICN. There is no use for them thus no value.
