If we do not need bitcoin, then what do you think bitcoin should run on? PayPal has a high transaction fee, as well as the others. Blockchain technology is fast and easy to use. I cannot imagine using other technology other than blockchain to run bitcoin with. Can you?
Agree. Blockchain have offered a different way of storing and transacting asset. The technology give us the full control over our funds and the need for third trusted party have been eliminated. This makes thing more simple and better, there in no one to intervene with you personal asset. It give us the freedom from any interest of anyone. This is why everyone should choose a wallet that provides the full control over the private key like Hodler wallet which is the fully open source multiwallet available. They also have hardware version of it for better holding experience.
Definitely, you are right. There's too many function blockchain technology on us that we must to adopt since we are now in a great innovation of adopting fin-tech and bitcoin is one of them that has a blockchain technology which is very useful on us. That's why you have said we must choose a good wallet when storing our crypto asset just to safe and our responsibility to manage private key which is very important.
