The problem with these is that similar to TOR, you need enough legitimate transactions to mask your traffic... because otherwise you can easily be spotted, which is why the TC website explicitly warns:

> After depositing, users should wait some amount of time before withdrawing to improve their privacy.

If you have 600 million dollars to launder, the probability of being caught is still massive. It simply is an enormous sum of money.

1. Tornado is self described as “experimental software.” I would not trust that protocol over a token designed around privacy like xmr. Especially with volume this large, timing attacks become a concern.

2. LE can still catch you on the way out. People are gonna start asking questions when you spend hundreds of millions in crypto.
