I think venmo is the biggest threat to bitcoin. If money over IP becomes prevalent without the need for bitcoin/cryptocurrencies, than the only benefit they really offer is for ideologist/criminals/economic reasons. But a lot of the added utility that we emphasize to the layman will disappear. And I ask myself, why don't we have that kiiler app yet?
then you don't understand Bitcoin.
Venmo still deals in USD which continue to be inflated by central bankers. not to mention all the identity issues.
money is meant to be a store of value, not a toy for vested interests.
