Then, when the first "shalecoins" are being moved, the cryptocommunity will discuss different topics: quantum secure addresses.
, if they succeed with this,
They will.
, correct me If I'm wrong they will have an opportunity to get the people's cryptocurrencies. right?
No, the first group will try to get the 'shalecoins', they have no owners. How do they know this? Nobody can, but if you move your coins to another address, they will know that there is an owner.
They could move coins from addresses with owner, but they will not. It would disturb the Bitcoin ecosystem and also the value of their coins.
Postquantum, nobody will be able to prove that he/she/they was/were the owner/s in the old system, because everyone will be able to reproduce the privatekeys.
We will have a quantum secure network.
This will be the new beginning.
