You have received great replies above.

Now I would like to give you something to think about:

Some people say that all cryptocurrencies are a ponzy or pyramid scheme.
The reason they give is that the more people buy the cryptocurrency, the price goes higher and the early adopters can profit by dumping at a higher price.

It makes sense until you think that the same thing happens with the real state market, fiat currencies and almost any existing product on earth.

Any thoughts?
