Oh shit, even below €1,000 transfer need to conduct KYC, who had submitted KYC to campaign managers?

I think you meant it as a joke, but as people often take jokes seriously, I link to the
newest proposal for reference so everybody can look into it.
The new "Obliged subjects", i.e. those who have to conduct KYC, are "crypto-assets service providers". This category of service providers is defined in the MiCa regulation (
Link to MiCa). In general, those obliged to realize KYC are (centralized) exchanges, wallets and other "custody" services, trading services, and financial advisors. Neither forums nor signature campaign management should fall into this directive, these are simply entities paying for services.
2025 will be different since many thing happens in this year e.g. taxing for miners, war on few countries, elections, and ban on privacy coins.
This EU AML directive reform will come into force in 2027.
Does it apply to all transactions or the €10,000 per month that the services currently charge?
I think here you confused two numbers. The 10.000 € are a hard limit for (single)
cash payments, and from 3.000 € on KYC has to be conducted on them.
Crypto service providers like those I in the EU will be instead forced to implement KYC regardless of the amounts operated, from 2027 on. But that is already partly the case, at least in most countries, because countries have their own regulations in place and many are already regulating these services.
