d'ailleurs, ça devient un sujet récurent : http://www.zerohedge.com/news/2017-12-11/no-bitcoin-wont-boil-oceansA recent report suggests that at current prices, Bitcoin miners will consume an estimated 8.27 terawatt-hours per year.
That might sound like a lot, but it’s actually less than an eighth of what U.S. data centers use, 1 and only about 0.21 percent of total U.S. consumption. comme ceux qui disent qu'une bagnole électrique consomme plus de CO² ... qu'une thermique. et les gens gobent ça tellement bien ... c'est désolant.

plus ou ... plus chaque jour en tout cas. raison de préciser les W et les Wh ... puissance instantanée pouvant être maintenue 1h dans le cas d'un mineur bitcoin ... mais pas pour un frigo, compresseur, groupe électrogène. Différence entre régime admissible (10min toutes les heures) et puissance crête (moins de 10 secondes).

les impôts automatisés, c'est très simple : tu fournis une déclaration de revenus et un robot compare ça avec la balance annuelle de toutes tes comptes déclarés. si ça diverge vraiment, y'a un appel europe/monde sur ta personne (ou entreprise individuelle ...) pour rapatrier des déclarations des "susdits" établissements financiers (exemple le plus marquant = Suisse, astuce = stocker en métaux). et quand ça veut pas : https://bitcointalk.org/index.php?topic=1858154.0

Descriptif encore plus précis des 2 "services" de contrats futures : http://www.zerohedge.com/news/2017-12-10/all-you-need-know-about-todays-bitcoin-futures-contractPRICE LIMITS AND TRADING HALTS
Cboe will halt trading in its contract for 2 minutes if the best bid in the XBT futures contract closest to expiration is 10 percent or more above or below the daily settlement price of that contract on the prior business day.
Once trading resumes, if the best bid in the XBT futures contract closest to expiration is 20 percent or more above or below the daily settlement price of that contract on the prior business day, the futures will be halted for 5 minutes.
CME will apply price limits, also known as circuit breakers, to its bitcoin futures of 7 percent, 13 percent, and 20 percent to the futures fixing price. Trading will not be allowed outside of the 20 percent price limit.

Rappel de ce qu'est un fixing : “CME Group's Bitcoin futures will be cash-settled, based on the CME CF Bitcoin Reference Rate (BRR) which serves as a once-a-day reference rate of the U.S. dollar price of bitcoin.
Since November 2016, CME Group and Crypto Facilities Ltd. have calculated and published the BRR, which aggregates the trade flow of major bitcoin spot exchanges during a calculation window into the U.S. Dollar price of one bitcoin as of 4:00 p.m. London time.
The BRR is designed around the IOSCO Principles for Financial Benchmarks.
Bitstamp, GDAX, itBit and Kraken are the constituent exchanges that currently contribute the pricing data for calculating the BRR.”
A reference rate / benchmark calculated in the City of London that is used as a basis for the settlement of multi-billion dollar financial contracts.
Wait, where have we heard that before?
