Post quantum custody leans into Coinbase Global’s security pitch, but leaves revenue impact unclear

For Coinbase Global, hardening Bitcoin custody against quantum attacks speaks directly to the Narrative catalyst that leans on security and institutional trust to support a broader “Everything Exchange” model. Moving early on post quantum protection can reinforce the case that its custody arm, which already holds a meaningful slice of on chain assets, is built for long term threats rather than just today’s exploits.
