RE: How governments can benefit by imposing a range of taxes on cryptocurrency
Australia is also planning to regulate cryptocurrency exchanges, which will provide more transparency and allocate more authority to the Australian Financial Intelligence Agency. - https://www.cryptocoinsnews.com/bitcoins-price-isnt-bubble/
The US Federal Elections Commission (FEC) issued its ruling approving the acceptance of Bitcoin as in-kind donations for political campaigns. As an in-kind donation, campaigns have 10 days to put the Bitcoin tokens raised into their official campaign depository.
In related developments, the FEC is assessing whether to amend its regulations on Bitcoin donations.
During their meeting in September 2016, the FEC commissioners have started their discussions on whether donations in the form of the virtual currency should be treated like cash. The agency has also announced that it will seek public comments on the issue once the proposed rulemaking is outlined. - https://cointelegraph.com/news/pro-bitcoin-us-congressional-candidate-starts-accepting-bitcoin-donations-for-2018
The tax fight has strengthened. http://fortune.com/2017/09/07/cryptocurrency-bitcoin-tax/
It is clear that some method has to be found to tax earnings, but expecting people to keep track of all their purchases and sales of cryptocurrency is very problematic.
Remember, all cryptocurrency is purchased from post-tax dollars in the first place. And it is very risky.
Only when very significant returns are involved should taxes kick in. Alternatively, the standard GST will capture all purchases and sales of real commodities.
