I have an account since 2016 and the reason I stick with blockchain is because their fees are fair for buying and selling Bitcoin. The customer service is all via email and sometimes is a bit difficult to get in touch as the options keep leading you to the FAQ. I believe the charts in app could be a bit better so you can see candle sticks and indicators. But I would recommend the app to friends and family.Finally, I would like to know more about security against hackers as sometimes we heard Bitcoin wallets were hacked and I don’t want to be the next. But again, it is a great app wallet and that’s why I am giving 4 starts
