That article (with fabricated quotes) shouldn't impact coins for which the public address has never been revealed.

Even if ECDSA is ever broken, you still would need the public key in order to crack the private key and to get the public key, you need a way to produce a valid public key that when hashed matches the address.

Or did Satoshi use public keys to pay himself? (I don't know).

But basically, value is only in danger when the public key is known and it isn't known from a Version 1 address unless you have spent outputs that used that address.
