Look at this diagram of the altcoins and their trading volume.
By coincidence, lightcoin had a higher volume than bitcoin the day of the survey.
This was posted on
Pantera Bitflash Weekly Review, where they said there are now 176 digital currencies, "
with another 15 in the queue". Grief.
I'm only financially interested in bitcoin, but I like some of the other names.
These are my favorites alternate names:
WorldCoin
Quark
BitBar
EarthCoin
NetCoin
