Yours CEO and co-founder Ryan X. Charles has said that Bitcoin payment channels will only be competitive with a block size increase of “ideally 1000x.”

In a post on the Yours site on Tuesday, Charles further calculated the value of a payment channel would likely need to be $150 “in order to be competitive with Stripe and PayPal.”

“We demonstrate that payment channels on bitcoin funded with $44 or less are not economically viable if they are used predominantly for payments in one direction,” he wrote.
