I think the simplest place to buy, sell, and store coins is Coinbase (and our tutorial below will help you get set up with that), but you can only buy, sell, and store Bitcoin, Ethereum, Litecoin, and Bitcoin Cash on Coinbase. If you are serious about trading cryptocurrency, you’ll need another exchange like Coinbase’s GDAX, Bittrex, Binance, or Kraken (and you’ll likely want to find a wallet to store your coins in). See a top 5 list of cryptocurrency exchanges and the Best Bitcoin Exchanges ranked (those above are my picks).
