It's for Speculating, Not Buying Stuff

I finally see the light! The scales have fallen from my eyes! In Google Autocompletes 'Bitcoin Buy', I wrote

Why suggest other means of payment (credit card, debit card, paypal)?

In other words, why use one means of payment (like a credit card) to buy something (bitcoin) to buy something else (as in Buying Stuff with Bitcoin)? Why not just use the credit card to buy the 'something else'?

There's a useful site at en.bitcoin.it/wiki which keeps popping up on my searches. In a post, How To Buy Bitcoins With Your Credit Card, I learned,

Intro: While in the recent past it has been risky for sellers to offer this option, some services are now allowing you to buy bitcoins with your credit card. However, that does not mean it is entirely risk free in all markets; if you are from Asia or Africa your funds may be frozen by credit card payment processors for further inspection due to the large amounts of fraud that come from those continents.

Note: If you only want to take advantage of Bitcoin's price volatility you can trade CFDs on Bitcoin via a credit card on sites like AvaTrade or Plus500. When trading online your capital may be at risk. Trading CFDs is suitable for more experienced traders.

According to Wikipedia, CFDs are 'financial derivatives that allow traders to take advantage of prices moving (see Contract for difference). So the main interest in bitcoin isn't to buy stuff; it's to speculate in the price movement of bitcoin. This was confirmed in a CoinDesk article, How can I buy bitcoins?

Surprisingly, it's still not easy to buy bitcoins with your credit card or PayPal, depending on your jurisdiction. This is because such transactions can easily be reversed with a phone call to the card company (i.e. 'chargebacks'). Since it's hard to prove any goods changed hands in a transfer of bitcoins, exchanges avoid this payment method and so do most private sellers.

It's not that the credit card companies won't allow bitcoin transactions. For them it's just another commodity or service that a third party is buying. It's the sellers of bitcoin who won't accept credit cards. Since they can't prove that they've actually delivered something to the buyer, they risk a chargeback.

Given that I'm not interested in speculating with bitcoin -- let's not use the euphemism 'investing' -- does it still make sense to look into it? I'll think about that as I continue this blog.
