You should probably add a disclaimer somewhere in OP. In no way does this represent actual people moving money for actual services, goods and whatever. It includes everything, including:
1) People moving money to their own (other) addresses/wallets.
2) Exchanges and other services moving their money.
3) Moving Bitcoin into cold-storage (can fall under both point 1 or 2).
and you forgot trading with zero fees, so selling in one second 100 bitcoin to buy it again couple seconds later.
Bots moving so fast coins that it building momentum in such graphs.
