I already knew about Waterhole, and after reading this article, it got me thinking - is it possible to make a profit using a Bitcoin escrow service? Like if I download this Waterhole app, is there an undiscovered opportunity for a larger return, compared to trading on a regular exchange?

Bitcoin escrows are a tool, which is used to solve a specific problem. And that problem is not to trade bitcoins at the most efficient price, but rather at the highest degree of security, which, I'm assuming, means that the prices of each trade there should have a larger spread, hence more opportunity for profit. What are your thoughts?
