Infinaty times zero is still zero.  Well, that is not quite true. "infinity" is not a number as such. It's a class of equivalence (of all the bijectives sets alike). To be allowed to use this, you must define what kind of infinity you are talking about, for example you'd say "infinity" = "limit of the function f(x)=1/x with x->0" And then, your "0" may well be a différent kind of "0" like "limit of the function g(x)=x with x->0" That is, "0" * "infinity" in such case = 1 for whatever x. |

As predicted, XRP is now entering the hyperbolic phase, lite-rally going to the moon. XRP stands head-and-shoulders above BTC. So long, bagholders.
Note: At this time, from pseudo_mah87's secret underwater base location in the Mariannas Trench of Bizarro World, the direction to the moon is -87 degrees azimuth. 3 degrees to go ... !  |

1. The price is, in my view, too high, because it is based on future expectations of fiat profit as opposed to backed by an underlying economy. Doesn't mean it won't go higher for the same exact reason it is already too high.
While the real compelling use cases for using btc as payment (eg bitcoin only markets, you know which ones) could hypothetically gain traction and make the btc economy worth the actual price.
2. The decimals are not going to be a problem. The consensus so far seems to use bits = uBTC. Redditors already tip each others in hundreds of bits (which is in the same league as USD cents)
Suppose you want to buy an aircraft carrier which cost $ 4 billions (or a set of buildings, or a firm, or whatever around that price) with BTC You'd need about 10,000,000 BTC which you'll have a lot of difficulty to get, and that's just one big transaction, nothing very unusual here. So I guess BTC's price will have to go up a lot if someone wants to be able to do real business with it. |

An other thing is that for geeks, or mathematicians it will maybe not a problem to pay a coffee 0.000000000198562 btc, of course here we still have double cash and information displays
Actually there is a problem here the geeks and the mathematicians will see : you can't pay less than a satoshi, so "0.000000000198562 btc" is just wrong. The minimum value is 0.000,000,01 BTC = 0;01 µBTC And two coffees are worth about 10 mBTC today, I don't see where the display problem is. |

 Et pourquoi une somme aussi dérisoire? Pour éviter que les partis politiques ne soient financés par des intérêts privés, lesdits partis leur étant in fine redevables, ce qui nuirait à la démocratie. Par une multitude de petits dons venant de la base, on garantit leur indépendance. Après tout un parti est censé représenter le plus grand nombre, il ne devrait donc pas avoir de mal à convaincre de multiples donateurs, sinon c'est chelou  |

Strange Monday at Huobi: a bit of trade in the morning and early afternoon, very little from 5:00 pm local time onwards. Usually it is the other way around, trade peaks in the late afternoon and evenings.
how do you notice that and not have any bitcoin totally blows my mind. In the late 1980s and early 1990s I spent as much time discussing space exploration on the USENET sci.space forum as I am spending here. Here is one of my posts from that time. By the way, "mining" then meant extracting precious elements from asteroids to build spaceships or space colonies. But no one ever told me that I had to put at least one satellite into orbit, or capture at least a small asteroid of my own, for my ramblings to be worthy of that forum. PS. In 1986 the internet was restricted to universities and some computer companies, such as DEC where I pretended to work worked, and was managed by (D)ARPA. There was no WWW; only FTP, e-mail, and USENET (a distributed bulletin board with its own protocol, UUCP). There were no anonymous users; if anyone misbehaved badly, other people would complain to his employer/university, and that usually solved the problem. Can you imagine an internet with no spam, no advertising, no phishing, no viruses, no webpages that steal your cycles to mine bitcoins, no silly avatars? In 1986 the first computer worm was still 3 years away. Sigh...  I bet you were a Millenium and Deuteros player  |

Au temps pour moi. tu as parfaitement raison. Voilà le bout de code qu ile définit. dans main.cpp : static const int64 COIN = 100000000; int64 static GetBlockValue(int nHeight, int64 nFees) { int64 nSubsidy = 50 * COIN; // Subsidy is cut in half every 4 years nSubsidy >>= (nHeight / 210000); return nSubsidy + nFees; } en 2030 (21 ans après le départ) on en sera à la 6 ème période, ce cycle distribuera encore 210.000*50BTC/32 = 328125 BTC, on sera encore bien loin loin du 21.000.000 ème Le calcul sera entaché d'erreurs de troncatures au niveau du satoshi après la 9eme période (50*100.000.000 = 0x12a05f200 ça laisse (nHeight / 210000) <=9 pour ne pas faire d'erreur, donc on ne l'atteindra vraiment jamais. Et maintenant on va se faire jeter par Boussac pour HS |

Pas mal de conneries oui, il nous explique qu'il y aura 21 millions de btc en 2030, et précise que le prix actuel du bitcoin est de 70$, je sais pas ou il l'achète mais j'attends voir, ils pourraient se renseigner un minimum ca frôle la bêtise. Dingue de voir comme les médias francais manquent indépendance d'esprit quand on voit les analyses de russia today ou même parfois certaines chaines US. Pour les 21 millions en 2030, ce n'est pas des conneries https://commons.wikimedia.org/wiki/File:Total_bitcoins_over_time.pngCe n'est pas tout à fait vrai. J'allais d'abord donner la réponse habituelle, à savoir que le nombre de bitcoin en fonction du temps est une fonction croissante qui converge vers 21 millions mais ne l'atteint jamais, mais j'ai vérifié les calculs. Il se génère un block toutes les 10 minutes, soient 6 blocks par heure, 144 blocks par jour, 52560 par an, 210240 + 144 = 210384 blocks par période de 4 ans, parce qu'il y a une année bissextile tous les 4 ans, coup de bol, c'est synchro. Le nombre de bitcoins était de 50 par bloc les quatre premières années, et est divisé par deux tous les 4 ans. Il se calcule donc par la formule : 50 * 210384 * (1 + 1/2 + 1/4 + 1/8 + 1/16 + ...) qui tend vers 50 * 210384 * 2 = 21038400 Trois remarques : 1) c'est plus que 21 millions, donc on dépassera 21 millions de bitcoins un jour. 2) Le nombre exact est en fait un peu aléatoire, parce que le nombre de blocks générés ne suit pas exactement la norme, le réseau peut être plus rapide ou moins rapide que ce que la difficulté prévoit, et le réseau ne "rattrape" pas les bitcoins en trop ou qui manquent. 3) 21000000 ~= 50 * 210384 * 1,996348 et 1,9963348 ~ 2 - 1/256 donc il faudra 9 périodes de 4 ans pour atteindre 21 millions, ce qui nous amène en 2009+4*9 = 2045 Voilà, pas 2030, mais 2045.
