I checked the Top 500 rich list on BitCore Blockchain Explorer
https://chainz.cryptoid.info/btx/#!rich
All addresses that show (at time of writing this post) the last change as 6 days and 11 hours have obviously participated in airdrop and have received their share of the 6% airdrop from last Monday.
There are however almost half of the Top 500 addresses (236 out of 500) that have not seen a change since 50 days or more.
1) Do I correctly assume that these addresses have not received any airdrop?
2) why would somebody with such large sums of BTX(range from 3000 to 77000) not register for airdrops?
Those are the btc holders that got the last 50% btc snapshot in November. Probably don’t even know they have them sitting in their wallets. Or can’t be bothered to import their priv keys.
