$100k a day is nothing in the terms of even a small economy - that being said, the entire discussion theme on these forums should be rephrased.

BTC are not an investment - they don't generate profits for a buyer without someone else putting money into them. This is true of all currencies, hence the tired "pyramid scheme" argument.

The demand in the market is ultimately dictated by what people view it's trade value as a currency is. Build applications for merchants/users that make this thing easier and simpler then a credit/debit card and you will see that value increase for the long term, unable to be controlled by speculators.

If you really want to contribute here, convince merchants to accept and support this currency in it's infancy. Develop payment networks that sit on top of BTC that allow for safety/trust in transactions with unknown parties. Support businesses that accept them by using them, if a business you purchase things from doesn't take BTC - send them an email asking them why they do not and if they have plans in the future to do so.

Use Bitcoins as a weapon to kill the paypal/cc mafia's and their exorbitant fees coupled with horrible policies. They leech money from the entire transaction economy increasing the costs for all of those involved.

Stop caring about the current PRICE of BTC/USD and only view what you want BTC to look like in the future, then build for that.
