Bit coin is still the most valuable cryptocurrency. Ethereum is still the most popular decentralized finance (Deify) ecosystem. Firstly I will recommend Cryptocurrency Investment Platform (coindex) as it is relatively new (launched at mid-summer 2017) but has become the largest cryptocurrency Investment Platform there is right now (total volume over 4 billion dollars) where you get 40% ROI of your invested cryptocurrency after 7 days. Supports variety of cryptocurrency like Bit coin, Ethereum, Bit coin Cash, Lite coin and other various crypto coins. I find that it has a really nice UI and support.

The most objective way to determine the top crypto currencies is to look at their market caps. For digital coins, market caps are calculated by multiplying the current price times the circulating supply. Here are the ten most popular crypto currencies on the market right now, according to CoinMarketCap.
