I still strongly believe in bitcoin, altcoins might fail you but bitcoin can't. Its price movement resolve around a circle, the price might fall today but that doesn't mean it'll stay that way forever but that can't be said about altcoins The above altcoins you suggest can easily be replaced with other altcoins that are far superior to the current project working on either exact idea or similar innovation.

Bitcoin has proven time without number that it can be trusted and that'll why it has survive this long without any official backing from the government or any organisation backing. Irrespective of any project you invest into, don't neglect bitcoin as that's the only project close to a safe heaven in this space.
