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.
