OP probably wanted to say that you may have to pay a tax on your cryptoholdings very much like you have to pay a property tax every year in so many countries. For example, if you own a few acres of land or a piece of real estate, say, a shabby cabin by the lake, these are all taxable. Though I don't know how any government is going to collect such a tax if it levies it on possession of crypto. I don't know if there is such a government, but it would interesting to see how things are going to develop in this particular case and what their mileage will be
As for myself, such tax doesn't make much sense as it will be very hard to collect and yet harder to prove tax evasion
Yes, tracking crypto holdings and assessing the tax liability is the real trouble for the governments. I recently read this article,
* Japan’s National Police Installing Crypto Transaction Tracking System - Bitcoin News.
But there is always a loophole for such system and hence the whole system is based on self-declaration and assessment in the initial phase, that would create chaos across the crypto community. As of now, in my country, we are taxed when the amount is converted into the fiat currency and there is no other way for the government to believe on the information furnished by the taxpayer assessee.
It will create chaos in the tax system itself before anything else. For example, here, in Soviet Russia (lol) the tax authorities have officially stated that they are not going to do anything about crypto and those who are involved in cryptocurrency operations. And it is not about possessing crypto and declaring it, it is about anything crypto related assuch including income tax on profits earned via cryptocurrency operations ("buy low, sell high"), the tax which you should pay in other countries lest you get in jail. Yes, it is an official position of the Russian tax service, and it is dictated by understanding that going after every potential tax dodger would create more problems than solve
So cryptocurrencies are officially tax-free or tax-exempt in Russia
The population of the Russian Federation is 147 million.
The working population is 71.8 million.
Millions of them are officially not employed anywhere and do not pay taxes.
Citizens of the former Soviet republics + Chinese, Koreans and other people who live without registration can not be counted (several million 2-5, read some opinions). They also do not pay taxes. All issues are resolved through bribes.
This is our country, and mining has nothing to do with it. Catching miners is a difficult task and not the most urgent problem.
