While I agree with so much of what you say, I think you are missing a main point. Bitcoin has the name recognition and first mover status. The problems you describe above will get fixed and when they do, so many of the altcoins...including Litecoin....will die. It is just not possible to have so many coins and Bitcoins problems will get resolved and it will maintain, and strengthen its dominance. Right now, it is speculation mania...when that subsides and we are left with the true benefits of cryptocurrencies, then you will see many altcoins disappear.
