SEC's Oct 1 custody proposal isn't about $BTC - that already had institutional rails. It's about the long tail of tokens no custodian would touch.

Registered advisers couldn't allocate to newer assets because custody didn't exist. Now there's a conditional self-custody path when no permitted custodian exists, reassessed quarterly, state-chartered trusts in the mix.

What actually changes:

Token launches get institutional demand months earlier - custody stops gating registered capital

Manager diligence shifts - if they self-custody, you're auditing their key management like a custodian

Crypto VC alpha window shrinks - native funds used to hold new tokens months before registered managers could touch them

Still a proposal, 330 open questions, final text could shift. But the custody wall that protected crypto-native funds' head start is cracking.

How fast it falls is the only question left.
