My interpretation was "as part of the payment system" referred to a payment system for illegitimate activities.
Otherwise why wouldn't he just say "eliminate cryptocurrencies."
Thank you for the correction, can you tell me was it "illegitamate activities as part of the payment system" or "illegitamate activities or as part of the payment system." so that I can correct it.
You didn't misquote it, I was just questioning how we should interpret what was said.
