What is better? Which one do you guys recommend more?
Thank you for your time
well, when you have some bitcoin you should also have some Litecoin. first is gold and the other is like Silver (people say that). normally litecoin follows his big brother bitcoin in the price
As for Litecoin following Bitcoin in price, take a look at this all-time BTC/LTC price-chart from BTC-e:
http://www.cryptocoincharts.info/pair/ltc/btc/btc-e/alltime
The trend you see is that Litecoin (and other altcoins, by the way) spike up a short time after BTC/USD has a large rally as traders are satisfied with their profits in BTC and want to diversify a bit. As the BTC-rally turns into a downtrend, LTC drops even more strongly in a gradual fashion. The largest peak in the chart not related to a BTC-rally is in july 2014, when MtGox hinted at Litecoin implementation. We all know how that went.
But the main message is that in periods where very little is going on, LTC gradually loses ground to BTC. This is extremely obvious in the chart and hints at LTC being used primarily as a vehicle for speculation in volatile periods and being primarily dumped by miners during quiet periods.
You need to take the distribution into account as well. In the end it is the people using the coin who give it value. If coin is stable and independent enough and community has reached some critical mass, it is unlikely that the coin will be completely abandoned. I agree though that the network effects will not allow the crypto space to expand indefinitely, but having a few good coins is definitely better than one (for reliability reasons).
