1. Wire transfer have very specific rules and limitations and for sure moving 3m$ isn't so easy as you propose it.
2. Face to face for what? Giving bags with cash to each other?! You are familiar with the term "dirty/black" money? Because banks knows it for sure!
3. Escrow...Who is going to be?

By throwing some random types of money transactions, doesn't prove anything. Especialy that you hold that amount of money.
We still waiting for you to sign the wallet that you hold these 2mil in BTC. I guess though that we will wait for a looong time...
