The first one is coinmarketcap.com There you can track the price of almost every cryptocurrency that exists. It's a very popular website among crypto investors.

Reddit and steemit are 2 website's i use for finding information about projects. Reddit is more active community than steemit but on steemit you can monetize your content. There are also a few interesting website's build on the steem blockchain you should check out. Dtube is a blockchain youtube alternative. Musing.io is a blockchain quora alternative. Then you got utopian.io where you can get paid in crypto to do some freelance work.

Cindicator is also a cool crypto application that i use. They have a website and mobile app version of their application. You can make predictions about certain cryptocurrency then they use those predictions with artificial intelligence to produce a prediction service for the people that hold the cindicator utility token. When your predictions are right you can earn some ethereum.
