is it a good time to buy ltc or will it stabilize at a lower price? and which is a better investment btc or ltc?
I think LTC is better because the tax is there lower and it have more chance to grow up than Btc

And Yes at the moment is a really good time to buy some LTC, because it is starting again to grow....
