The market has decided , Litecoin is number 2 and once litecoin goes on Coinbase even more money will pour into it and less into other crap coins.
I would love to be able to buy and sell LTC on Coinbase. Is this a reality and if so, when?
The creator of Litecoin Coblee works for Coinbase and he has hinted that when the time is right Coinbase will support Litecoin. My guess is sometime in 2014.
