Wally Come on wal. People just fire up their browser and hand over loads of data to google. That’s how the internet works. And if you want to use the dark web you need to have some more understanding.
Bitcoin is entirely traceable thanks to its public ledger.
First you need to buy some, then put it in a wallet, but not a wallet that somebody might run off with, then you need to launder it so that the bitcoins you purchased using your debit card are not actually traceable to you, and they get used by a russian mafia gang instead, but get traced back to you (that is season 2 of this thriller) and then you need to hand over your address to somebody who posts narcs through the post to you. I cannot see any potential vulnerabilities in that at all.
