I don't have any control about which coins I spend so my best bet would be to put it in some sort of mixing service that I read about in the forum a while ago. Am I correct about this?

Thanks for the answer.

You could have the bitcoins sent to a mybitcoins account, and then transfer it to another bitcoins address of your choice, in segments/installments.

Mybitcoins just use one wallet.dat(as far as I know) and keep all details of your transactions and account with them internally(in a database). This would mean a number of bitcoins come and go from this one wallet(everyone who deposits or withdraws bitcoins from them), and there is no way of knowing that any going out are yours as long as you break up the amount.

For example, you get paid 100btc into a mybitcoin.com account, then in maybe 3 payments of 20btc, 30btc,50btc to your own personal bitcoin address. There would be no way to know that those coins are yours except getting mybitcoin.com's account records.

It's actually a kind of bitcoin laundering. Someone will set up an automated service for this soon enough, if it's not done by the summer then I will set one up, call it bit-laundering.com or something ahahahahahaha

Heh, that's mine

It's simplistic for the moment. No guarantee you won't get the same coins you send, but it does add a bit of complexity to the history of any given coin.

Oh no, Nefario, if you think 1% is too high then you should be very keen to operate your service for 0.9%.

There's another one called CoinTumbler at the Onion address: http://lbrmvt4plqojaulx.onion/

So what if it does? Then taxation is not necessary because government as we know it, don't exists. We must reorganize society on a different basis.

For a libertarian, it would seem Utopian, but for everyone else, it seem scary.

Well, a better future is not going to be comfortable and boring, but crazy and scary.

Crazy and scary does not mean 'dangerous'. By the time we reach that stage, it will be "normal". Of course, today's audience would think it is crazy and scary.

If people knows what's going on in the 21st century 100 years ago, they would think it is the wildest and craziest story imaginable.

The bitcoin economy will grow and prosper precisely because it has the potential to facilitate a parallel economy that can also operate beyond the scope of taxation. All types of transactions will be attracted to a taxation-free zone because throughout history no- to low-tax zones have always thrived against their counterparts (Hong Kong, US in the 1800s).  This parallel economy will know no political borders so it will not even be clear which taxation authority has the jurisdiction over the economic participant(s).

Even if the proper jurisdictional taxation entity could be reasonably determined, they would still be faced with applying a tax to a reusable proof-of-work 'puzzle'. Firstly, how do you tax a mathematical puzzle without giving it monetary legitimacy?  How do you determine the political borders of the recipient key (if recipient is careful)?  How do you determine the total amount to tax if bitcoin laundries and mixers are used?  Today, an individual can work for bitcoin in anonymous fashion from an undetected geographic location and then spend bitcoin or anonymously trade out of bitcoin.  I don't really see that changing. I'd be more worried about an authoritarian shutdown of the IRC network.

It is no easier to avoid taxes using Bitcoin than using cash.
