both coin are potentially to hold,though they crypto market is volatile now,but we wil see a change in the near future,litecoin can be hold for a long term investment which you can benefit massively when they value rises.
I would say on the contrary that bitcoin is suitable for long-term investments. Litecoin is possible for some speculation in the courses. And I generally think that Litecoin will gradually lose its positions and leave the top 10 crypto currency. In the future, bitcoin should also give up its leading position.
