Amount of tax also depends on your jurisdiction and accounting methods.

If you are concerned about it, a local tax professional can provide you advice in writing, which if you rely upon, will be proof of any intention to evade taxes.
This is why paid advice is worth more than free advice from internet lawyers, (who are not your lawyer).

Having provably no intention to break a law means that it is not going to be a "criminal" problem even if you are wrong, at most it would be a civil fee.

Probably you don't.

"Consumer protection" is the buzzword used by industry incumbents to protect their industry by using the local governments' authority raising the barriers to entry.

Generally it results in fewer choices for consumers, and less competition.  Very often the result is that there are no good choices remaining.

Pre-emptive Consumer protections tend to accomplish the opposite of their legislative intent.

End state is closer to US$5M/bitcoin, but we get there by investing rather than holding.

QFT and mined for the gold.

It is very rare these days that someone outside the core team is so helpful to them as in this post.  Most outside core would be just as happy to see core fade away instead of being so very helpful as TB is being here, albeit TB was masterfully trolled by GM into doing GM's job for him, it is just as likely that GM's ego or outside incentives will prevent him from taking any of this helpful advice to heart.

Most interesting here is that TB has found where Core team have added the Big-O Quadratic Sighash bug which is their big issue of why then need SegWit and can't scale.

GM shoots Bitcoin in the leg, TB shows him the wound, the blood, the gunpowder marks on his hand and hands him the surgical kit.
GM sits there mocking him and shrugging.
Bitcoin's blood leaking out while GM stares around wondering why he doesn't get more love.

Law is a matter of geography.
If you need a law, it depends more on which ground your feet are touching than anything else.
Most any cryptocurrency transaction can be separately codified in a document to be filed with your local authorities.

Zooko has a point here.  There are trade-offs, but these are only some of the concerns.
Take Monero for example.  It is CPU/GPU but the CPUs do better for the money invested.
The issue with it is that it is highly mined by botnet.

If Bitcoin goes the CPU route with its economic heft, it will encourage botnet mining to a significantly greater extent.  This could have consequences for public relations, legality, VC investment appetite and other problematic results.

If the goal is to 'forever end the specter of miner influence on development direction', CPU PoW change might not be radical enough of a change, Bitcoin might have to go one of the more tested PoS methods, or find another solution to the Byzantine General problem.

If PoS is chosen, the longest successful, tried and tested PoS chain is probably Bitshares, which was refined again for Steem.

If a CPU PoS is chosen, may the governments of the world have mercy upon Bitcoin.

May the peace that surpasses understanding, and the grace of the most high, flow from the giver of all good things to His loving people.

Incremental increases in block-size will work to avoid the sighash verification attack so long as the blocks fill up not too long after each increase.
(So bumping blocksize up to 2mb or so now should be fine, then again larger later when 2mb blocks are reliably full with TX fee paying transactions.)

Why?
The sighash verification attacker forsakes the TX fees in order to get the coinbase miner subsidy.
Larger full blocks are the swiftest and surest way to move to a TX-fee supported network.
When this occurs, the incentive for this variety of attack goes away and blocksize is no longer limited by this attack vector.

How?
Simple increases (as Satoshi suggested back in 2010), manually introduced as needed, will work just fine.
The main criticism of this is that it is central-banker like activity, however as shown, the need for this manual activity disappears in a finite amount of time in the relatively near future (when bitcoin becomes a fee-supported network).

For those that did not hear the resolution of the Liberty Dollar case.

The judge did not overrule the conviction handed down by the jury.  What the judge did instead is essentially nullify the penalty in the sentencing.

It seems that Judge Voorhees was utterly convinced of Bernard Von Nothaus's innocence.  However if he overruled the jury verdict (as is his right as the 13th juror.  The prosecution did not prove their case on any of the counts.  There was no intent to defraud, no intent to conspire, nor to counterfiet.  There were in fact no victims either of any fraud nor counterfeiting nor conspiracy.  Despite the charges not being proved by the prosecution, the jury was overwhelmed by the show of force of the prosecution with FBI, Secret Service, and very expensive prosecution lawyers (especially when compared to the lawyers provided to BvNH after all his wealth was seized by the government and could not afford to pay for more).

So instead of overruling the jury, which would have resulted in an appeal, perhaps a new trial, and likely another decade of litigation taking what is left of BvNH's life time, the judge split the baby by cutting the sentence to nil.

BvNH and all the customers with gold and silver in custody were awarded their metal back.
No prison time served.

Basically, free to go without any penalty other than the conviction on his record.

The entire process was a great travesty of justice, and abuse of power for political reasons.  A private business was punished due to the free speech of its founder who advocated for the National Organization for the Repeal of the Federal Reserve Act (NORFED).
For saying the same things that many senators and representatives also say, a private citizen's life and legacy were destroyed.

Fortunately he is back in business and as dangerous as ever.
Now he is exercising his free speech with a "Trump Dollar" in gold, silver and copper.
It was released during the 2016 primary season long before Donald Trump was even the nominee.

I am not involved in this, other than as an admirer of Bernard's artistry, but it seems to have had some success.

There is a key issue regarding legal tender which might help some of the explanations here.

If a Bitcoin issue ends up in a court of law in a country that has a legal tender law similar to the USA, (most all countries), litigants are required to accept the legal tender of the state, in any dispute, as full compensation.  (This is the effect of "Good for all debts public and private")

This means that anytime a court is involved, the bitcoin can be sold and the government cash substituted as payment in full to whomever wins the case.  The value at time of transaction in the local fiat currency will be the important point to determine the amount, and should be one of the facts determined by the court.

Perhaps you could expand on this?

If I were "them"...
The unmarked cars or aviation would come into the area for installing electronic surveillance on wireless devices at the minimum.

They would arrive, linger for a minute or two once in range of devices with a femtocell, and then leave.
There is simple and cheap technology for doing these sorts of things available to all law enforcement.
http://thehackernews.com/2016/01/drtbox-cellphone-interception.html

There is a fun project underway for detection/countermeasures against these that is quite useful for protecting a geography you control.  It already does most of what you might want and is not so expensive.
http://hackaday.com/2016/08/09/how-to-detect-and-find-rogue-cell-towers/
Much cheaper than castle walls.

If a castle wanted a more active defense, HERF devices are very effective against most vehicles.  It would have to be abandoned.  If flying it would likely crash and be messy.

The detection of these sort of active defenses is such that it would benefit from underground wiring so the heat from the wire would not draw a line to all of them from higher altitude infrared scanning.  A good amount of capacitance at the device location is useful, so that it would still function if the wires were cut.  As with any technology, maintenance and testing is the ongoing chore.
Just some fun things to think about.

The Kek is strong in this one.

I have nothing to hide, I have much to protect.

The "you have things to hide" argument is authoritarian pablum.  It presumes that the law enforcement is ever present and entirely protective.  It assumes that you can never protect yourself.  Does the person who says this leave their valuable objects in clear view in their car overnight.  Do they walk around naked?
Privacy is important for so many reasons, it is not about wrongdoing, it is about survival in a civil society.

PHYSICAL bitcoins are those coin shaped bitcoin wallets made popular by Casascius, usually made of bronze or silver.  They may or may not contain bitcoin because in recent years, there was some legal hassles for Mike where they want him to register as a MSB.  Consequently he sold them without bitcoin in the wallet for a while.

So a "funded" physical bitcoin is one with bitcoin sent to it.

What I don't understand is the people that are suggesting that he sell these on an exchange....   

It probably is not illegal where you are, but there are different forms of "legalization" that may be used to "legitimize" bitcoin.  Two of the more important of these are "Legal Tender" and "Lawful Money".  Legalizing in this sense just means that you apply a pre-existing body of law to it.  It is already legalized in many ways everywhere.  If you break a law using bitcoin it is probably going to bring just as much trouble as if you used some other thing to trade, so it is legalized in that sense already everywhere.


The OP does not specify their country.  Each one presents different challenges, however as soon as the first nation state with an international exchange recognizes Bitcoin as a "legal tender" then all other countries that do exchange with this country also defacto recognize it as lawful.

Legal Tender law is a horrible thing and has resulted in tragic tyranny through out its history.  Under the banner of 'standardization' it has primarily been used to force a constituent population to accept something valueless as if it had value.
In the USA there have been great legal battles as to whether a paper currency that was not backed by specie (precious metal) could be deemed legal tender.  The battle was lost most everywhere and LT law constitutes an unlawful taking from the people by their government, degrades that government away from solid metrics of value for their economy and thereby sows the seeds for financial ruin deep into the national soils.

Bitcoin may be the answer to this for any nation member of the world bank that deems it to be a Legal Tender in their jurisdiction, no matter how small it be.  The first nation to do this will win the jurisprudential lottery forevermore, and the last one to do so will lose.

Legal Tender law is a horrible piece of government, but the best governments are those that also govern the government, itself and force it to do good for its people.  By this mechanism of making Bitcoin a Legal Tender, the Legasy of Legal Tender law may redeem itself by bringing solid metrics back to government standards everywhere.

Another designation is "Lawful Money".  Jurisdictions that have this designation use it to categorize monetary forms that "may be accepted lawfully".
Legal Tender designates monetary forms that the government REQUIRES its citizens to accept for settlement of a debt.

One is allowed (but may be refused), the other is allowed and may not be refused (but in most jurisdictions you may also accept any other currency by contract, such as bitcoin).

MimbleWimble is a proposal for an altcoin or sidechain.
It calls itself bitcoin out of hubris but isn't.
It is baffling me how people accept that.

The Duke has requested that one coin from each type, for which he has a quantity >45, be added to the prize pool.
