Do freshly mined Bitcoin cost more?

[Italian Panic]

I have come across different costs depending on whether the bitcoins are freshly mined rather than older bitcoins or satoshis that have changed hands several times (too much hop).
One of the issues in the crypto sector stems from AML checks that are triggered when tokens are transferred via centralised exchanges such as Binance, Coinbase and Kraken, which analyse the funds' history and trace their origin to assess how legitimate they are. The problem is that you might receive bitcoins or fractions of bitcoins for a service you've provided, and some of those outputs might have a poor AML score, which would then trigger a whole process to prove that they do not have an illicit origin.
Browsing the web (not on the clearnet), I have found sites where they sell miners Bitcoin at a slightly higher price, between 5% and 10%.

What do you think? What would be a correct high percentage?

We or other long-time crypto space people know that when we deposit on any cex platform, it is their job to first trace where the coins we are sending to them come from, and they know if it comes from hackers, ransomware and others, and once they detect that it comes from a bad source, they will hold it or freeze the assets at once.

And you are right that this can happen to people who are not aware or do not know that the only thing they are transacting is that the origin of the coins turns out to be from a bad source, then in the end these innocent people are the ones who will have problems due to the address given to them turns out to be dirty.
