I think it's too risky to buy Litecoin at this time. New crypto-currencies offer something new but Litecoin doesn't even have any upgrades and new offerings. It's pure speculation but I don't think it'll go over 10$ again, ever.
Upgrades and offerings are irrelevant to what makes a good currency. Is the US Dollar or Euro a bad currency because it doesn't have any upgrades or new offerings?
Does not matter my friend, LTC does not needs something new, it's working fine, strong coin, reliable, stable, etc.
New coins with with upgrades like you are saying, we have tons of, check on
www.coinmarketcap.com, new coins, new upgrades, bla bla bla, big shit brother, all useless coins...
Litecoin and Bitcoin is like USD and Euro, just working FINE with our without upgrades
If you want upgrades, buy pre-mined shitcoins like Ethereum, Lisk, etc.
Litecoin and Bitcoin are working fine, its what matter, thanks to ask
