There's a lot of websites I use on a daily basis. Here's a list of my favorites in order of their use:

Market Trends

1. CoinMarketCap - easily see how a coin is performing, what exchanges it's currently listed on, and links to other official or useful information.
   

2. OnChainFX - similar to CoinMarketCap and ATHDA, where it has summaries about each coin and useful links, it also has a filter for scam and possible scams which is helpful for identifying which coins to avoid, and has a mobile friendly version.
   

3. CoinLIB - nice interface and a helpful tool for doing comparisons between coins.
   

4. ATHDA - a quick reference to see what the ALT (all-time high) is for a particular coin.
   

News

1. CCN - the latest cryptocurrency headlines from around the world.
   

2. LedgerStatus - insightful articles and a deeper look into cryptocurrencies.
   

Exchange

1. Binance - fantastic interface, easy to use, with a wide selection of coins (referral link)
   

2. KuCoin - my favorite in terms of interface, however the selection of coins is sometimes limited.
   

3. Cryptopia - their interface is just okay, however they have a great selection of lesser known coins (referral link)
   

4. Bibox - a newer exchange so their coin selection is still low, however their pleasing interface compares to KuCoin.
   

5. GDAX - nice interface, great for trading BTC, ETH, and LTC, and useful for avoiding transfer fees associated with Coinbase.
   

For the exchanges, for transparency, I separated the referral link from the main website. No need to click on either but I do appreciate the referral.

Please let me know if you have any questions. I'm always on the lookout for new websites so please feel free to share your recommendations.

Thanks for reading!
