The original purpose of Bitcoin was to safely pay for minor purchases, such as say magazine articles.
I never saw a need to buy Bitcoin to make a tiny price purchase.
That was the general idea. You would purchase $20 of bitcoin for example and spend the next month or two paying a few pennies a pop to read newspaper or magazine articles.
Everybody was to be happy under this arrangement. Content creators would get their revenue and consumers would be able to read articles "a la carte" without having to have monthly subscriptions for every publication (which nobody can afford).
Those micropayments add up too. If a content provider charged .04 per article (four cents) and got a hundred thousand views on it, that would be $4,000. Multiply that by 20 or so articles a month and you are starting to talk real money. Especially if you can attract millions of readers.
Somehow bitcoin went in a totally different direction and became an investment vehicle for some reason.
