Some of these altcoins will become the future of digital currency. Bitcoin opened the door, but its lead won't last.
The main thing these coins need at the moment are people, ... people investing, volunteering, and working within the communities.
That is for sure. Some just bring new technology and die (if coin can die), but that technology continue improved in some other form.
The main thing coins need at the moment are not just people, but people with ideas. If 99% of coins are used just for trading on exchanges what is the point of investing, volunteering, and working within the communities.
Whole this block chain technology should change how people think of money, not just letting them play with it or acting as all this is great ponzi scheme.
Good thing is that there are good ideas, but in the sea of scams it is hard to see right one and believe in people behind it.
