Normal People, Family & Friends
People like you and your family use Bitcoin to transfer earned income and savings directly to their children, without government intervention.
Normal People, Whose Savings Are Being Destroyed By Inflation
People like you and your family use Bitcoin to to preserve their savings from inflated fiat currencies.
Except that BTC is tied to those inflated fiat currencies, and is far more volatile than any other currency. One day your savings will be worth 100,000 and the next they're worth 90,000. If you bought BTC when they were really high then you lost more than 50% of your wealth.
Normal People Making Small Purchases on the Internet
People like you and your family use Bitcoin to conveniently purchase individual songs and other intellectual property on the internet.
Waiting 3 days for a wire transfer, and then an hour for confirmations to clear is far from convenient. I'd say Itunes has this covered, if you're going to pay in the first place.
Businesses
Businesses use Bitcoin to avoid expensive chargebacks from dishonest credit card purchasers, and to lower the cost of doing business.
Not sure how the cost of running a bitcoin business is any cheaper than a fiat business.
Refugees from Repressive Regimes
People trapped in corrupt jurisdictions use Bitcoin to protect what they have earned.
Really? Do they just set up their desktop in the middle of the refugee camp?
Philanthropists and Other Generous People
People who learn about genuine suffering use Bitcoin to eliminate the middle-man and send anonymous contributions instantly to wherever they can help.
Which isn't a lot of places. As far as I know no medical charity organization accepts BTC. You won't be donating to red cross or MSF any time soon.
Journalists and the Media
Journalists and the media use Bitcoin to provide incentives and protection to Whistleblowers.
I don't know about this.
Travelers
People who travel for business or pleasure use Bitcoin to reduce the risk of carrying cash or credit cards.
How? Unless they have memorized their wallet they need some physical way to keep track of the address and private key.
Here's the real major groups that use BTC:
InvestorsPeople use BTC as a commodity or stock, instead of a currency.
Drug UsersPeople who want the best strains of weed can purchase it anonymously and easily.
GamblersPeople who don't want their gambling activities to be public can also use BTC anonymously for transactions.
