Quantum computing a threat to bitcoin? I don't think so.

 When we're real close to perfection in quantum computing, and it starts looking like a big threat to bitcoin, we (the bitcoin community developers) can:

-hard-fork bitcoin and create a tangle (like that of IOTA or a better form of DAG) based coin.
-air-drop it to bitcoin addresses with 1:1.

It does look like a possible solution to me.
