Random as in you don't really know if someone is paying by using multiple tx? That I agree with. But i'm more concerned about the average transaction by anyone using it.
I'm trying to verify the evidence that Ive read in support of The Lightning Network stating those micro-transactions should be off-chain. I want to know if its true that as many as 70% are <$100.
step 1: know which output is change and which is not. Just pulled one from bc.i

Does it pay 0.01 btc or 174.... btc? Most likely 0.01 since its a round number, lets take another one

now which is the change and which is the payment?
Unless you can resolve this, you cant find an answer to your question.
