The same tendencies that keep people away from bitcoin keep some bitcoiners away from LN.
  • LN advocates oversell Lightning as infinitely scalable and problem free today.
  • Skeptics are impatient for mass adoption and declare new tech dead early, just because it hasn't taken off as fast as they expected.
  • LN incentives are more inclined to centralization than Bitcoin's.
  • Some may worry that LN will undercut Bitcoin's security budget.
