I believe that people start up cyrptocurrencies because they either want to make some money or maybe experiment with the internet. It's basically like when a scientist test run a new gadget. It still is amazing how these cryptocurrencies live though. What do you think?
Some are just for money , some are going to change the world, it's up to the coin developer.Anyhow , if you want to invest in an ICO, do a research about the coin at first.
