In my opinion we use bitcoin, beacuse bitcoin is the firsted and saifest way to make money and it's also have safe transection also. we also use bitcoin because we can convert bitcoin into any currency in any time and in a small transection fee.That's why we don't have to carry our money with us in any wallet of bag. we also don't have to any big rules like bank . Because bank give us a lot kind of rules for hold our money or any kind of transection.So i think we should use bitcoin to make our life more comfortable, thank you.
