Coinbase is one of the worst exchanges for beginner and intermediate traders. Coinbase is also one of the most used exchanges. Here are some reasons why you should never use coinbase.
The only reason you could argue coinbase is useful is that you can buy using a debitcard. This is good but you only have a $100 dollar limit per WEEK. After you buy with your credit card and pay the $3.75 fee per $100, you will transfer it to bitconnect or cloud mining etc. Coinbase charges a base fee or 4% for all transactions. Here is a chart showing fees per transaction type.
This is considerably more than any other exchanges fees. Also you doubling the fee because you have to buy it and transfer your bitcoin. Coinbase also monitors your transaction history. If they think your using bitcoin for gambling or something els they don't like they will cancel your transactions or worse ban/suspend your account.
Transaction times are significantly LONGER than other exchanges. To test this I sent 0.0026 bitcoin to a blockchain address to convert it into STEEM POWER and it took 4 hours to complete the transaction
Another reason to stay away from coinbase is because they provide minimal data and inaccurate charts, combined with the high fees this is the worst site to day trade/swing trade on. I recommend other platforms like Poloniex, and Bittrex.
In conclusion, coinbase uses new and inexperienced traders to there advantage offering a cheap, safe, and secure place to store bitcoin.
