I would add some other topics also:
- influence on the state currency
- using of the bitcoin for criminal purposes in the country
I agree that bitcoin is using by criminal purposes, Because all of the transaction here is hidden. The criminal dont need to be afraid to kill someone to get money with no evidence at all by using this by paying them.Money is all in the world and some of the people doing bad things just to get more of it.
it is small amount if compare with total money circulated in cryptocurrency.many people spread news about crypto usage in criminal case. less than 2 percents maybe.
