Note2: Title of thread is incorrect. Should read "Does Bitcoin increase wealth inequality"
Then why you don't just change it?
And no, bitcoin won't change much imho. It does give the chance to some "newcomers" get rich, it also makes some of the wealthy wealthier.
Since it gives more chances to almost everybody, it's imho less "unequal" than stocks. It may be closer to what gold was in the early years of the gold rush.
