It is totally impossible that they impose a tax on bitcoin as they do not accept bitcoin as a currency for their country and they do not have any control on any wallet or maybe some wallets. They can do if they start accepting it for their country and will start their wallets.
Maybe in some place, but that is not true in the U.S. Diamonds are not currency either. However if you find a diamond you owe taxes on it. Any wealth you gain is taxable in the U.S.
i like to think about bitcoin, like i think about cash that i found on the street, sure they should be declared,
but do the IRS will ever know about it? i don't think so, so it's up to me if i'll declare them or not and the trouble that i might get by deciding to not declare them, still if i not use them nothing bad will happen, no one will ever know how many bitcoin you have
It is quite likely that they will eventually find out
I'm not a US citizen so take my words with a grain of salt, but you should be very cautious in respect to whom you transact in cash with (on the other hand, it is readily applicable to anyone anyway). If I'm not mistaken, any deals involving cash in the amounts exceeding 10,000 dollars should be declared to the IRS, regardless of whether you are an individual or a company. You may not know this, so when you buy something, say, a car from somebody with cash for so much, your seller may declare their income, and the IRS might go after you at the end of the day (to inquire about taxes and where you got this money from)
10k dollars in what time frame? if within a year, i think many poor people are there, so they are not forced to declare, otherwise everyone must declare, i would personally do a transaction with anyone but not reveal my identity, so i'm safe in case i'm dealing with an officer
As I got it, there is no time frame altogether (but I can be mistaken), i.e. every deal or transaction in cash equal to or exceeding 10,000 dollars should be declared separately. About a year ago, this question had been discussed in great detail here, and I posted a pdf file from the IRS site with a form which should be filled in such cases and concise explanation how and when exactly it should be filled...
If you are interested, you can easily find this pdf in Google
I think he meant in one purchase. Purchases of currency or anything over 10K will trigger all sorts of investigation. If your caught you will wish you had paid. Failure to do so is way more expensive.
Don't mess with the IRS
