The technology itself is not sinful, and the guilty ones are those who use it.
So I don't think there is a direct link between the bad guys and the bad guys on the blockchain ledger, which doesn't mean that bitcoin is bad.
We have the same logic. Bitcoin will not be bad in the blockchain, those people are. Yes, they want income and they use an illegal way for it and they use bitcoin as a payment. So whatever happens, bitcoin is not the one who did it, it is always the person.
Yes bitcoin and blockchain technology are not malicious and wrong as long as nobody abuses it, which makes bitcoin negative by laypeople like that, they run illegal activities using bitcoin as a means of payment or transact. So if they (the laymen) are tracking blockchain and crypto technology, I'm sure they'll aware and not always see the bitcoin from the downside.
