Elliptic Curve Digital Signature Algorithm - Bitcoin Wiki

"If ECDSA is broken, Bitcoin can remain reasonably secure if you don't reuse addresses." Is this true?

If this is actually true, what makes it true?
That post is pretty old. Has anything significant changed? What's the recommended best practice these days if you need to reuse an address? For example you are a business and need to have a single address that can be published and it wouldn't be practical to keep constantly changing it?
Is this also actually true: "(That is, an address's sent transactions might not actually be meaningful, related to its receipts, or even made by the person who receives money at that address.) "? If so, why would that be the case? It sounds like the OP is suggesting an address can somehow "send" bitcoins that it never "received" - how can that be?

Time to replace ECDSA with with post-quantum cryptography to secure the future of Bitcoin.

Crucial hurdle overcome for quantum computing
The development of scalable quantum silicon chips is moving faster than expected. ECDSA is considered broken by Shor's algorithm. Upgrade Bitcoin before it's too late!

[12] P Dikshit, K Singh Weighted Thr eshold ECDSA for Securing Bitcoin Wallet National W orkshop on Cryptology (2016) [13] H Ghodosi, J Pieprzyk, R Safavi-Naini Remarks on the multiple assign- ECDSA is used across many security systems, is popular for use in secure messaging apps, and it is the basis of Bitcoin security (with Bitcoin addresses being public keys). ECDSA is also used for Transport Layer Security (TLS), the successor to Secure Sockets Layer (SSL), by encrypting connections between web browsers and a web application. Security of ECDSA: A note on existential unforgeability. There are no known proof of ECDSA’s security in the RO model. This may be surprising, given ECDSA’s usage in bitcoin. Here too, similarly to DSA, the belief that a security proof may be difficult to construct rests on our inability to date to successfully leverage the reduction model. One of its main supporters is the cryptocurrency system Bitcoin which uses an elliptic curve scheme for their digital signatures. Smaller key size, a more efficient implementation than the RSA system, and a similar level of security make elliptic curve cryptography an interesting alternative to RSA.
