&gt; There is no reason for individuals to buy&#x2F;sell Bitcoins other than speculation.<p>You already listed one other reason - drugs.<p>&gt; What would be the point in buying Bitcoin with cash&#x2F;card only to use it on a service that also accepts cash&#x2F;card?<p>Only a handful of online services sell gift cards through brick and mortar stores that you can actually purchase with cash.  As for the point of not using a card - my main interests in bitcoin as it stands today are:
  - I don&#x27;t have to share my identity with the service I&#x27;m purchasing from (to validate the credit card), increasing my privacy and anonymity.
  - Like cash, it limits the risk of fraud and dark patterns (hidden fees, reoccurring charges that you weren&#x27;t expecting, outright fraudulent charges, etc. don&#x27;t simply auto-deduct from your account - although you can still not get the service you paid for.)<p>Well done, friction-free micro transactions for some services (e.g. news websites) might actually convince me to start using bitcoin regularly.  Of course, that hasn&#x27;t happened yet - nor do I know that it will happen with e.g. the problems with dust etc.
