You think there are a lot of coins already?...Wait till larger companies want their own coins for the own rewards or payments purposes...We are only at the tip of the iceberg right now.. Larger companies will also have the resources to handle mining themselves if need be, or to give incentives to miners to drop coins with no future or use. Looking forward to it..:-)
It is kind of scary also(and exiting). FB, Goolge, AT&T, etc. are already major communication/media companies. Imagine them with control over a monetary system as well.
