From user side, they need to move their coin to "secure address". But from technical side, there are few dilemma such as,
1. Should we freeze UTXO with vulnerable cryptography or let it stolen?
2. Should node/miner reject transaction where the output contain "old address" after "secure address" is available?
Shouldn't we come into an agreement
now instead in a stressful period when everybody will scream for the sake of their money? I mean, do we have to wait until it becomes feasible enough to break the secp256k1 or rather gather as nice, calm Smurfs and vote for our decisions?
Yeah, not only that but they're really not worth changing over to since they still pin their entire security on a hash function which is no different than bitcoin right now. They say you only use a private key/public key pair in Lamport once but we all know how that turned out in bitcoin. people reuse their addresses they do it all the time.
And what does the reuse have to do with the security of a hash function?
