LTC is good, especially right now the price is great to fill your pockets with this coin. I believe that LTC, ETH and BCH would be the first three coins that would boom after the new beginning of a bulltrend, that is hopefully coming in the nearest future.
when the market enters an uptrend not only the 3 coins you mention will increase. even all altcoin can and have the same possibility to increase. but that depends on how the developer responds to incoming bulls. if the developer can maintain and increase the community and that request will be good. but if they are no longer trusted by the community or their community is weak it will be bad even though the bull pump is running.
LTC might be good, but seeing things that don't go according to plan, I think some of the community of supporters also has less trust in developers.
