As if Coinbase doesn't rob people enough with all their fees, now they are charging customers multiple times for the same transaction. It's funny they made this mistake and didn't mistakenly send the customers extra coins.
This article from The Verge tells you more about the double charging incident.
Coinbase is a business and they are excellent in their business. They are so good that when someone asks me how to get any crypto coins I tell them to start with buying bitcoin or litecoin on Coinbase, despite my hatred of Coinbase. I only say this because unless you have a friend in front of you wanting to sell you some coins, Coinbase is the easiest way to get coins. It's so easy my dad can use it.
Coinbase is a great way to buy coins but I encourage everyone to transfer their coins out of Coinbase ASAP. The point of bitcoin is to be in control of your funds. If your funds are in your Coinbase wallets then you aren't really in control of your funds. Now you rely on Coinbase when you want your funds instead of purely relying on the bitcoin network. Your funds could be out of your control if not stolen if Coinbase were to be hacked.
Please look into safer storage options if you currently keep your coins in Coinbase. Hardware wallets are a great option. Converting it to Steem is also a great option.
