So to be clear I know very little about the deeper mechanics of crypto. I am trying to work out if Amazon accepts BTC if it will help or hurt. On one side I see that it could help as it would shove bitcoin into the mainstream creating an explosion of growth of users. On the other side if Amazon hordes wealth like they already do there will be much less bitcoin in cirrculation. While this may cause the price to spike due to rariety at some point bitcoin may become unusuable for smaller transactions due to limited quanity. If there are only so many coins in exsistance once they hoard so many there would be things that would cost less then the smallest unit and would be a possible death of the coin.
