While ECDSA is indeed not secure under quantum computing, quantum computers don't yet exist and probably won't for a while. The DWAVE system often written about in the press is, even if all their claims are true, not a quantum computer of a kind that could be used for cryptography. Bitcoin's security, when used properly with a new address on each transaction, depends on more than just ECDSA: Cryptographic hashes are much stronger than ECDSA under QC. Bitcoin's security was designed to be upgraded in a forward compatible way and could be upgraded if this were considered an imminent threat.
