Bitcoin in its early appearance was paired with pizza.

Pizza = buying children/ illegal activity.

Castello is also a famous cheese.

Velveeta then does this.

I think they are setting up the comm:

Gold = cheese = yellow.

When they talk about cheese and yellow things they are talking about gold. They are desperately trying to set up a comm to talk about gold. Gold can also be a comm for money.

If they need to covertly talk about gold that badly, then they're probably having a cash flow problem.
