Without Bitcoin's positive trend, those alts would not increase in price. No need much explanation, you already knew which one is better.
some time i'm confused , suddenly bitcoin drop and all alt's are up and suddenly bitcoin price down all alt's drop or up , so confusing in cryptoworld.
Simply dropped to test its support and not because bad news. So bitcoin is still in a good time and yeah altcoins made a killing. But the answer of your question "which is better for the future?" is always Bitcoin. It also the safest one for long-term investment. However if you want to make easy money, you can trade shitcoins. They will give you more profit once get pumped somewhere on shit exchange.
For those coins you mentioned, Bitcoin the the best option but Doge is not an option because it has no real use. Litecoin is always following Bitcoin, Ripple has no new development but has a potential get a sudden pump with news, and ethereum... is facing struggle. If you are looking for the price, beside to choose Bitcoin, perhaps you could choose Ripple. But, I personally won't invest in Ripple, never.
