they shouldn't add anything to their site, it is crushed already. They need to open another exchange site for new coins. However i mean why do we need any other coins?
Unless a coin shows some innovation what is the point of it anyway, there are already too many clones.
Why? because they can
or more pragmatically, greed
Many people outside the cryptocurrency world are getting to know about it from the mainstream media, but even if you have a decent pc with a decent GPU you are out of the game with BTC or LTC. Ok you can get a few cents but the time for mining those coins is getting to an end at least for the average Joe. With alt coins you can still feel the excitement when you hit a block and get lots of coins
What will happen to the hundreds of altcoins in a few years is an interesting question, after all many altcoins manage to survive much longer than anticipated, the ratio of dead altcoins is surprisingly low so we are going to get a little too clogged with new altcoins up in the next months/years.
As long as they are not scam coins with the only intent to make the developers rich, it's fine for me
