1) Early adopters may have stashes of millions of bitcoin. If widely adopted a few super rich could have a huge influence over the whole bitcoin economy. Imagine owning 5% of all USD in circulation(with no fed to inflate).
"Only the man who does not need it, is fit to inherit wealththe man who would make his own fortune no matter where he started. If an heir is equal to his money, it serves him; if not, it destroys him. But you look on and you cry that money corrupted him. Did it? Or did he corrupt his money? Do not envy a worthless heir; his wealth is not yours and you would have done no better with it. Do not think that it should have been distributed among you; loading the world with fifty parasites instead of one, would not bring back the dead virtue which was the fortune. Money is a living power that dies without its root. Money will not serve the mind that cannot match it."
