That's a good idea for the usage of Bitcoin now. Actually, we can deny the advantages of Bitcoin. As you know , Bitcoin is still illegal in several countries and even is banned. However, Bitcoin now is not taken taxes, so the governments do not make income from bitcoin. Do it become to deficit budge ?
The magic of bitcoin lies in a system that was never thought of before, where financial transactions did not involve the government or banking. This is amazing, bitcoin breaks the run money theory wherever it can be traced. It turns out that bitcoin can get rid of everything. So, there is a good side but there is also a bad side. The government must be more rational in looking at bitcoin and immediately find ways to get bitcoin users to be taxed, because taxes are a source of state revenue.
