The logic of litecoin advocates is self-defeating: for litecoin to prosper, it must wrest its market share from bitcoin (remember it is almost a carbon copy with minimal changes).

• If this is not possible, then litecoin is worthless.
• If, on the other hand, this is possible, then litecoin is also worthless (along with all other cryptocurrencies), because hundreds of new altcoins will appear every year, diluting the market share of bitcoins, litecoins and all other altcoins.

In other words, Litecoin is an interesting experiment on indirectly bypassing the Bitcoin emission limits. If this experiment succeeds, this means that emission cannot be meaningfully controlled in a decentralized way and all cryptocurrencies are therefore worthless.
