This could lead to a bad reputation of altcoin since the founder himself sold all his litecoin. So, obviously those who already know about these may seems to started to have doubts investing in this coin. But still, nothing can really determined the outcome of crypto since it is already circulating in the market and definitely it has still a chance to grow. In terms of popularity,  I think it's pretty obvious that ETH is the answer. So, I am still in favor of these two good coins to invest it in longer term because crypto is getting more useful as the years are passing by.
