I would prefer not to have any of these coins because I believe that they do not have a prospect in the future cryptocurrency market
I disagree, ETH for example is one of the most used cryptocurrencies and has a future for sure. So many projects are based on it's platform erc20 and you need always ETH network for transfers. Many updates are incoming for ETH next time.
But ETH is before LTC, because use case of LTC is much less compared to ETH.
