After doing some breakfast reading about Blockstream's Liquid and complaints about flaws in Lightning Network something hit me. Is there a second hidden reason for Liquid that Blockstream plans to make money off of? Some estimates had 50-60% of bitcoin being locked up in Liquid Bitcoin but it is it truly locked? What's to prevent Blockstream from lending that bitcoin? A major issue with Lightning Network is that you have to have money to receive money. There are 2 ways to do this. Fund your own channel or get another party called a swap provider to do it for you. What is to prevent Blockstream from becoming a swap provider and use that huge pool to make money by lending it to those that can't afford to fund their own channels? Now they are making money 2 ways.
