Let's prove him wrong.

-- See idea below.

In Season 9 episode 23, an entrepreneur pitched a business, "CoinOUT" to the Sharks. { https://www.coinout.com/ } which
basically turns your small change in coupons or back into cash. The Sharks debated and Mark Cuban commented, that cash
will never disappear and that not even the Bitcoin Freaks, believed that. Guess what Mark, we do believe that...right?
Now that got me thinking... Why not turn your small change into Bitcoin?
Someone can approach the guy from CoinOUT and ask him if he wants to add the option to cash out to Bitcoin. If he does not
want to run with that idea, we simply get our own Bitcoin developers to write a plugin for the most popular point-of-sale
software to offer people a option to get their small change in Bitcoin.
The wallet providers can offer their help, by providing a secure wallet at registration for this service and the payment
processors can even add their support by adding options to convert BTC back to Fiat, if the customer wants that. The
local exchanges can even provide services to sell the BTC, if certain pre-configured "sell" triggers are reached.
The loose change left behind at airport security checkpoints adds up to big bucks: $674,841.06 in 2014, just imagine if that
could have been turned into Bitcoin.

Let your small change, work for Bitcoin.
