SIFMA wrote to SEC's crypto team, opposing Coinbase and Kraken's bid for tokenized stock exemptions.  
They called the requests "deeply concerning" and urged SEC to gather public input first.  
No fast-tracking approvals without transparency.  
Big policies shouldn't skip rules via waivers.  
SIFMA also doubts SEC's ability to oversee unregistered firms and protect investors.

Wow SIFMA really cares about fairness, pushing for public input and transparency before any crypto decisions are made that’s so thoughtful
