No coin has reached its highest value and I believe LTC will go higher and higher. If you sell and you will not run and a lost then you can but if you will run at a loss then why sell it? Patience is key in this venture.

Bitcoin is high up in the skies and it is difficult to reach it. And considering the fact that Litecoin has a future, it is then advisable to consider it in terms of investment so that one day if it also hits the skies, you would also soar with it. But never will I choose LTC over BTC. We don't choose students over masters.

Looking at the history of LTC in 2017, it was able to rise by 7,291% where it hit $320 for the first time. Therefore it is likely to hit $500 this year.

Early this year, the founder of LTC, Charlie Lee tweeted that there is “One huge unexpected surprise” coming in 2018. We do not know what this surprise is yet, but we don’t think he would have tweeted this if there wasn’t something exciting about to happen! But the founder of Ethereum are not also going to sit idle. LTC can never overtake ETH. LTC has a great future though but to stipulate it will overcome ETH, is a no go zone area.

I don't get what you mean but I think you are trying to ask whether litecoin is a good coin or a bad coin. Litecoin is one of the successful coins in the year, 2017 which increased its value by more than 5000% in just 12 months. Considering its success in 2017, I think it is a good coin to invest into.

Every coin we envy today had a beginning. And ripple like any other coin we envy today had to start from somewhere. So today that the future of ripple is a bit dicey, is the time to buy ripple. And you need patience too.

It is believed that ripple is being used by over 100 companies around the world and to remove ripple from the system will not be a good idea at all.
