Bitcoin has been having significant impact since it was created in 2009, but only those that hold it knew this at the time.

How? Even most people still convert Bitcoin to fiat for daily spendings, and when using p2p, people also interchange fiat and Bitcoin, I do not see how this is a problem. People that are core Bitcoin users still do not have options than to make use of fiat for so many reasons. So, how will fiat be affected when people are still making use of it for daily purposes?

Yes, but most people are using exchanges and custodial means to buy cryptocurrencies, this should not be a problem. Also there are many fiat based businesses evading taxes.

Most countries are not yet taxing Bitcoin and crypto investment in general for now, but there would be amendment in the future. I think taxing cryptocurrencies investment in US has been effective. The taxing is just like normal taxation, but the taxing can differ from one country to another.

Do not forget Binance can track your capital gain, they can comply with the law of a country, and people to report their capital gain and pay their tax.

You are right, anything custodial makes Bitcoin not to be pseudonymous. Bitcoin is not anonymous but pseudonymous.

Yes. But people do not care about the pseudonymity, that is why trading volume on decentralized exchanges are not much compared to centralized exchanges. Even most people that are using decentralized exchanges first bought cryptocurrencies from centralized services.

This kind of discussion is already present on Bitcointalk.
Already in 2012, here, in Defend Taxation, taxation was described as extortion.
Furthermore, Is taxation theft? debate already has 1351 replies.

This thread topic is how is taxation possible and its relationship with the so much wanted anonymity.
So please don't derail it, there are places you can express that opinion about taxation. And keep in mind that I don't disagree with your opinion.

I think it is difficult to calculate crypto taxes, one thing that is impossible if there is a crypto tax,
and basically crypto is anonymous, how does the state know who will or who owns bitcoin crypto
the government will also cheat in this case the common people will be asked for crypto taxes while , they will pay crypto taxes or not  if they have crypto assets

There are still some countries that seems to be okay with bitcoin but don't have much regulation towards taxation. But for those countries that you have mentioned, they're becoming strict towards bitcoin and strengthening the policies that they've made because they see that it's an emerging market and there are a lot of citizens of theirs that are earning from it. Having that said, they cannot ignore the potential that they can take advantage of it through taxation. As long as you're living in a country that's very fine with bitcoin transactions and don't seem to be strict with it, I think you're living in alike paradise because you can move freely but declaration of profits/gains are voluntarily done.

My country is still in the setting stage. The rising price of bitcoin and its users is the reason for the huge income from Crypto taxes. Since taxes are the main source of state income, they are too serious about big money flows.

Meanwhile, for now, tax reporting is still limited to how we report it as income tax. So we can include or not include it. But I'm afraid that if this is done right then I'm a little doubtful how it works. If it is true that the exchange is cooperating with the government, then I think there will be vulnerabilities regarding confidentiality.

In my country tax on Bitcoin is implimented on the profit I make, its called Capital Gains Tax.
As long as we use banks and exchanges that insist on AML and KYC regulation our
anonymity is surrendered. Buying Bitcoin and selling it again with the FIAT then transferred
to a bank account means the whole transaction is traceable and liable for some form
of taxation depending on a countries rules.

Beginning in 2017, tax authorities began to take this unprecedented income seriously. At this point, you'd better make sure that you do everything related to tax filing right. It is now in the tax season in the United States, and the Internal Revenue Service (IRS) will not let go of this part of the income they deserve.

Here we use a third-party app to cash out BTC to paper money and aside from the conversion fees that are gonna be involved, we're getting taxed when we cash it out from certain remittance center that are near us.
When you use a third-party app, you had lost your pseudonymity, not anonymity, because most likely you're gonna need to undergo KYC verification.
Government won't let you just net out hundreds or thousands of cash.

Bitcoin should be taxed,because Bitcoin should be treated the same way any other financial asset is being treated by the tax authorities.We have to face the truth-Bitcoin is a financial asset,rather than a currency.
If you want to know how other countries are taxing Bitcoin,just do a research.Don't ask questions on a forum.
Bitcoin isn't anonymous.BTC mixers can make it anonymous(but only if the Bitcoin mixing service is reliable).
