OK let me explain how money works because people seem to think that Atomos = Inflation. Which in a way is true. If you were given an easy way to get a lot of GC seals your going to use it.

Because everyone is out waiting for Atomos to pop they are spending less time doing other things.
Less time to gather items.
Less time to spirit bond.
Less time to craft.

People with money are still buying items they need because its convenient.

With a much lower supply of items and little to no change in demand the ward are selling out causing prices to go up.

As far as people selling crystals people are making money off of these but its just another commodity.
There is no money getting added to the system because the only way the at money is added is by killing mobs with gil, selling items to npc's, or doing quests.

Money is just changing hands now in great quantity on an item that is easy to obtain but high in demand.

SE only mistake was to create an event there servers could not hand and had to remove one of the best rewards from it. While 3K clusters were still available the price of crystals was going down. I was not even turning mine in I was saving them B/C they offer a nice attack boost. Once Clusters got removed the demand for crystals went up so there prices rose.

Bottom line is that all the stuff on the AH can be obtained your self. Yes some you need a group for the drop but there are people who need items that you can sell to them and then buy what you want that's the cycle.
