Neither am I too, I have not really come across that case that will make me consider some of these coins for investment or usage because in the long run, they all do end up depending on the main bitcoin to grow in value including some other altcoins too, so if they have to depend on bitcoin, why then do I not just continue to hold and make use of the main king of coins that has already cut across all areas of usage.
Majority of this fork of Bitcoin, I do not really see them lasting longer than 5 years in the market, same as some other altcoins too. Once Facebook coin is released now, only bitcoin and maybe Ethereum will be able to compete with it, because other coins are not strong enough to withstand the strategy of the digital coin that Facebook is planning to release into the market.
