@chytrik The docs show the USD price for the AntMiner and the powet supply, on the day I bought them... That amount was converted into CAD by FedEx at time of import. Taxes and duties were then calculated on that amount.
@MaxVernon Thanks for the info! Good to hear thats the case, if the USD price on the label was calculated at the shipping date (or whatever else), it could make for some terrible import fees in BTC prices jumped between purchase and shipment!
@fredsbend why not build a plugin that mines a CPU/GPU-algo altcoin? Probably won't be efficient enough to actually be competitive with dedicated mining rigs, but I think it would still be many orders of magnitude more 'profitable' than a bitcoin mining plugin of the same sort (assuming you don't burn out your laptop's chips).
@murch You can absolutely transfer ownership of BTC without a transaction. I suspect you mean "on chain" - but ownership is very different from control of private keys.
@NicolasBarbulesco If I met you in person, perhaps.
@NicolasBarbulesco If you buy BTC on an exchange, you will own it, but the exchange will control it (in the same way that you own the money you have on the bank, but they control it). You can however withdraw the BTC from exchanges to a wallet of your own, where you control everything.
Whether you want to trust a particular exchange with control over your money is another question of course.
@PieterWuille You are correct. I guess that implies transferring the ownership of the private keys. So the receiver would have to trust the emitter, to be sure that no copy is kept. That transfer of ownership without transaction is what will happen if a bitcoin owner dies and has a heir. Am I correct?
@PieterWuille OK for meeting in person. :-) In France?
@NicolasBarbulesco Here are some examples of ways you can transfer ownership, without having a transaction confirmed into the blockchain: bitcoin.stackexchange.com/questions/67057/…
@MeshCollider Thank you! But the page en.bitcoin.it/wiki/Private_key says otherwise. See the § before "Contents". It says that even a perfectly hidden private key can be a risk.
@fredsbend If you include your own transaction without a fee, you trade your own transaction for including something else that paid the fee. The opportunity cost matches the cost of a fee, but that way has the disadvantage of your transaction only being attractive to yourself. If you just add the fee, anybody might pick it up.
@PieterWuille Well, yeah, an opendime would work, but I'm not aware of a generally available protocol that allows you to transfer private keys trustlessly without meeting in person, i.e. that prohibits the seller from keeping a copy. I remember our discussion with the hardware wallets that could implement this, but afaik this was not shipped, right?
Oh, reading the rest of this, I'm way behind the conversation.

@chytrik Nice write-up.
I guess one could mail an OpenDime, but then either the seller has to trust the buyer to get paid, or the buyer has to trust to receive the OpenDime.
@PieterWuille Oh, and I just realize that you were hinting at off-chain. Of course you could transfer on a centralized database or in LN.
@Murch And the buyer would have to trust the maker of the OpenDime. S/he may have looked into it before sealing it, or something like that.
If I buy a bitcoin at a platform, like Coinbase/Gdax: I don't pay a transaction fee, but I pay one the day I want to transfer the bitcoin to my own wallet, correct? And if I never do so, but sell my bitcoin back to the platform, do I pay a transaction fee?
@NicolasBarbulesco Generally, to change the control of bitcoins, someone must pay a transaction fee. Some platforms pay this for the user and charge them a flat ~$1, some take the fee out of the sent amount, some take even on top of that. As long as you only claim ownership but leave it in custody of your business partner, you don't pay a transaction fee. However, you may pay a trading fee.
I don't trade much, so I don't know the current fee structures these days.
@NicolasBarbulesco Most people seem to like hardware wallets lately.
They are obviously a bit of an investment at first and you have to make sure that you get one that's not been tampered with, but then they work pretty well
Paper wallets are perhaps a good substitute to that if you don't want to store too much.
I guess my question doesn't get much more complicated than this: Is it "frowned upon" to ask a lot of questions and not answer other people's questions?
@Murch I've seen a number of articles recommending downloading an .html paper wallet generator, followed by turning off wifi connections, and then running the .html page offline to generate printable paper wallets. To me this seems like a terrible idea, a faux-cold wallet that is at risk to any malware that may exist on your machine.
I think I would be more comfortable storing coins on an iphone mobile wallet, than a wallet generated on my laptop... less chance of malware? Anyone else care to weigh in?
