Now we can see some countries are regulating bitcoin and some government don't like it.Otherwise Bitcoin hasn't a stable price.
So my question is can bitcoin be a main currency of world economy?
How economy drive is created?
Its two way transaction where people within the country earn money through there jobs, skills, business and they pay taxes over their salaries to government. This is also followed by the employer itself who pays government X share for doing the business in their territory and thus government earns more money from different ways. When there is international trade then other countries pay local government for doing business and trades with them.
These all creates the stream of investment for government and using which they pay government employees their salaries, create big infrastructure, roads, bring oil into the nation and puts up education system and much more.
This generate the proper circle of economy and an ecosystem is created here in regulated manner.
Bitcoin and Economy?
Being decentralised and running over the public ledger bitcoin becomes partially invisible to the government. People dont pay nay taxes over it and thus money flows in one direction only. People can save up as much money as they want and as long as they dont convert back to the fiat then they re not eligible for the taxes. Thus it disturbs the ecosystem that we discussed above.
In no way bitcoin can help future of economy.
You said a lot of good things and when you get to the bitcoin part, you forget that bitcoin can also help a lot. I'll give you an example: if the government and the banks of my country were encouraging bitcoin exchange and miners to settle in my country, it could be an advantage for my country, as exchange and miners would be creating jobs and to encourage universities to create blockchain courses, crypto there ... there would be more software engineers and banks too would be moving more money, but because of the political elite this is not going to happen.
Now we can see some countries are regulating bitcoin and some government don't like it.Otherwise Bitcoin hasn't a stable price.
So my question is can bitcoin be a main currency of world economy?
My answer is never. What can we expect in a currency that comes from a market that has so much fraud and is always manipulated? The disadvantages of Bitcoin and the Crypto market are heavily exploited. So Bitcoin's future is bleak and we should not invest long term on it.
so it's dark bitcoin or do you mean that there are people with obscure intentions who use bitcoin for malefic purposes? because bitcoin can not hurt anyone
