Bitcoin advisor Luke Broyles said on the Coin Stories podcast that doubts about whether Bitcoin can further rise have persisted for years, even if the price reaches millions. This doubt may continue, and change may require "extremely long time." Broyles believes that the biggest obstacle to Bitcoin is not technical, but psychological, because most people still do not believe it can improve daily life. "Unfortunately, I don't think many people will make a change until they see it with their own eyes."
