I honestly don't believe anyone actually uses any of these alt coins. Covals main focus is instead of hype to get real usage and admittedly that usage is zero so far. So seriously is anyone actually using any of these platforms. I highly doubt it which means the whole thing is bullshit speculation and likely to crash.
Every coins differ from one another,there are coins specifically for one industry,there are some coins that has already created a merchant store of their own and some of them are for tipping purposes only,maybe time will come when online transactions will be focussed on altcoins also .
