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.
Plenty of investment options for everyone and we don't need to worry too much about rankings. Bitcoin is currently leading the market and this position will never be changed because this is the first coin in the world to be recognized. I think in the future the position of all other altcoins may change but Bitcoin will always be in the number one position. I trust Bitcoin because it is a coin that always helps me to make good profits
