Sure, but what was the advantage to you of using BC over any other currency to complete the transaction ? (Prior appreciation does not count since it was not part of the actual transaction). Where was/is the comparative advantage ?
The advantage is its being stored in fluctuating (appreciating) assets so you can continually compound your wealth while accessing it for payment of goods and services. You can move in and out of different cryptocurrencies and its a 24 x 7 market.
speed - accessibility - convertibility - convenience - control - privacy - wealth accumulation.
People like control, governments, banks, institutions, intermediaries, brokers etc all get in your way to some degree.
You cant do this, you can't do that with your own money.
You can't transfer your money there. That will be $20 for that wire transfer.
Banks are notorious for unexpected surprises on your account, dishonored charges etc
You get 50 million security questions every time you call a bank for assistance.
You cant day trade with under 25,000, sorry. Please complete and sign these 20 legal documents.
Brokers love giving unexpected charges and fees. Sorry, didn't you read the fine print.
With cryptocurrencies you have complete control and personal accountability of events and processes. That's what people want in this day and age.
