The problem I see is that we can't just keep adding crypoto currencies indefinitely.

The market place is a wild west at the moment propped up by people looking to get in on the next coin early enough to ride a big boom.

The problem is that this is artificial. To have long term, sustainable worth the coins must become useful to mainstream society and the sheer number of alt coins will put people off.

I'm looking for coins that garner mainstream coverage and coins with the best underlying technology and infrastructure.
