I quit agree with you that Bitcoin is not expensive but it depends on the person in question. A person who can afford 1 Bitcoin without fraction, may see it as cheap because he can afford 1 of it. But a person who can not afford it even in the smallest fraction will see it as being overly expensive.  or I can say Bitcoin is not expensive for those who finds it convinence. It's just simple, people should just buy the little fraction they can buy comfortablely than postponing Bitcoin investment. Those that keep on procrastinating about Bitcoin has already learnt their lessons, so anyone who fund it difficult will later regret on why they never bought Bitcoin when they have the opportunity.
