Millions of BTC that can't claim will have their HEX's value paid to stakers. As of 9/29/2019:
Only about 12.6M BTC of the 18M total bitcoin could claim because MultiSig can't claim (most exchanges), and GoxMeNot, etc.
What's left gets hammered with SillyWhalePenalties since 42% of Bitcoin is held in addresses of over 1,000BTC. See Bitcoin Rich List.
2.7M BTC in addresses over 10,000BTC pay their 75% penalty to stakers. That's 2M BTC worth.
Roughly 4.8M BTC is in the range of 1k-10k BTC addresses, and gets hit with 50%-75% penalties they pay to stakers, let's estimate it at 62.5%, so 3M BTC worth.
So we're already down to 7.6M BTC of claims effectively. But wait, there's more.
4M BTC is thought to be lost, 1M BTC is thought to be Satoshi's (likely deceased.)
LateClaims hits for 2% of their possible claim every week they don’t claim.
The moral of the story is that Stakers will multiply their HEX stacks on day 353 when all these bonuses get paid to them. About 2/3 the Bitcoin supply worth of claims or more.
Bitcoin has several different address types. The majority of bitcoin is held in addresses that can be used to FreeClaim HEX. Some Bitcoin address types cannot FreeClaim HEX. 66.3% of BTC is in addresses starting with 1. 8.69% are in addresses starting with 3 or BC1 of type: P2SH or BC1 wrapped P2WPKH. Most exchanges and whales/institutions use multisig, which is not supported. HEX gives the common man a chance and pays the Stakers all the coins that can't or don't claim!
