At what point in the podcast does Leo smash bitcoin?
It is at 47:25. The host Leo seems to actually like Bitcoin (he was one of the hosts in that great Security Now show about Bitcoin.) Instead, he criticizes the cash/Bitcoin exchange markets which, he thinks, are mostly used for money laundering. Here is the actual quote (the context is within a segment of the episode where they are talking about alternative currency / money transfer sites like WebMoney, Liberty Reserve, and how they are used by crooks to sell illegal software and services):
You know Bitcoin, which is very interesting, we did a whole show on Bitcoin at Security Now.
I think, really, because you can generate these Bitcoins on your Mac or any computer with spare cycles.
And then there is a a market for Bitcoin in cash.
And the only reason I could think of why that would be is because that's a great way to launder money, you know.
