Mate we are here to learn and also ensure that we pass the knowledge we grabbed to another person, so the content of these work is Bitcoin problems have to be solve, so our question should be what are the challenges of bitcoin so that we can know the specific place to be tackle before solving the problem, in general what kind of problem does Bitcoin facing, because from news no challenges for now except the fees of some cryptocurrency which are extremely high such as ethereum, Bitcoin, and ripple, so if challenges of settling the problem is the problem Bitcoin had, I don't think its something that can be handle easily.
