Everyone who wanted to sell have already sold within 1.5 years.
not all ico investors have claimed yet , so some who have had tech troubles are still waiting for manual claims. Might be some coins cheap from those guys, would be interested to know number coins still unclaimed.
It's damn easy to use a IOTA light wallet, also a Android light wallet is available. It's easiest to claim with them. Some have so much money that they buy and forget what they bought.

you see, this is just an excuse.
it's crazy and by the way it's only a few % was not claimed now.
IMPORTANT FYI: "
