Bitcoin is definitely top rated in the industry currently, and is unarguably the first or number one coin. I think if we are to measure pother altcoins that follow suit in no order, then we must make mention of altcoins like Ethereum, Ripple, Lite, to mention a few. I think there are a good number of altcoins doing great in the market currently and I personally cannot overemphasize on the need for anyone to make their research and the one that works best for them.
