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?
I guess it is because all they want is to have the same thing with bitcoin popularity and money that bitcoin produces. How everyone wishes for that of course because even me I really want to create my own crypto currency and make a big name. Also these days making an Altcoin and earning in an ICO and then through exchanges is a good business and many people are creating lot of profits from this activity.
