This app is good to buy and sell bitcoins but not soo much as this app has very high fee to buy bitcoins and a very big difference between buyin and selling of bitcoins. The good thing is that it has a six digit passcode entry but as you know where there are pros, there are also some cons. The price of bitcoins fluctuate, but this app does not show the exact price of bitcoins but sometimes its good for buying as it gives higher selling prices also. Overall I will give only 3 stars to this app. Its not so good if u want to buy and sell bitcoins regularly!
