I think any alt coin that was released after about june 2013 is most likely a waste of power and time.

I would only suggest mining an alt coin if it has a distinct upgrade compared to LTC. I would not mine any sha256 coins as they are old technology compared to scrypt.

I look at these alt coins. It just seems like they get mined to death, dumped onto an exchange after 3 months, then no one wants to buy them any more and they become worthless.

I know everyone wants to make the 10,000x profit but it just isn't going to happen. If there is a new amazing coin invented, it will be mined so hard and fast that you wont be making $1,000,000 off of it because so many other people will be mining it.
