Cryptocompare.com is pretty good. Essentially, you make an account there, and every day you are emailed updates in the cryptocurrency world, which I find quite useful. Also coinmarketcap.com allows you to check concrete figures like which coin went up or down and by how much, as well as things such as daily volume and market cap. Also, just keep an eye out on this forum about which coins are being released and talked about etc.
Those you were suggested is really good perhaps I already apply it on myself and I can say that it could help to those who are into crypto world. Most of them has a good condition it terms of being updated in terms of pricing.
