Now go ahead and list the disadvantages. They are far more powerful. Terrorist links, money laundering, tax evasion (serious since without taxes you wouldnt have many things that you take for granted everyday,) . . . not accepted throughout the world only in a very minute part of the population.
You seem to be confused. What you have described there is the United States Twenty Dollar Bill. Or perhaps the Twenty Euro note? In other words you are describing attributes of currency, any currency. Clearly these attributes are not getting in the way of widespread use of these currencies.
What you people dont understand about inflation is it will exist anyways with or without bitcoin. Since the cost of goods are going up regardless itll just take more bitcoins to buy the same good.
Saying that inflation will always exist, and that the cost of goods are going up regardless, and that it'll just take more bitcoins to buy the same good doesn't make it true. As a matter of fact, it is pretty clear that you have already been proven wrong, as it already takes less bitcoins to buy something than it did 3 months ago, and it took less bitcoins three months ago than it did 6 months ago, and it took less bitcoins 6 months ago than it did a year ago. Clearly, you need to re-think what you are saying here.
. . .only 21 million coins possible
You are mistaken here as well. In reality, Bitcoin moves the decimal place eight places to the left just to make it easier for us humans in these early days when bitcoin is dealling with really big numbers. Given the current protocol, with no significant changes in the future to divide into smaller units, there will be nearly 2.1 quadrillion whole coins. That should be enough for a very long time.
Bitcoins isnt revolutionizing anything its just a cool concept. If it was then bitcoins would be far bigger than it is. Most people have never even heard of bitcoin.
How long does it typically take for a revolutionizing concept to catch on from it's earliest beginnings as an experiment until it is in widespread mainstream use? I can think of a few examples (electricity, telephone, internet, radio, automobile, aircraft, etc) and none of them were all that big 4 years after someone first came up with the idea and tried it out. Can you think of a single revolutionizing concept that went from experimental idea to widespread mainstream use in less than 4 years?
