IIRC public keys are only revealed on bitcoin once you authorize an out going transaction. There are large bitcoin addresses that have never revealed their corresponding public key such as https://www.blockchain.com/btc/address/37XuVSEpWW4trkfmvWzegTHQt7BdktSKUs https://www.blockchain.com/btc/address/37XuVSEpWW4trkfmvWzeg... As long as you never reuse an address bitcoin would continue to be resistant to quantum attacks even if you can factor private keys from public keys, you still need to invert a hash function to go from address to public key.
