Il existe une faille “fatale” dans les crypto-monnaies, à cause de laquelle elles ne pourront jamais constituer de véritables monnaies » – Business Insider | 10 048,88 $

« Le pro­blème auquel sont confron­tées les cryp­­to-mon­­naies, c’est qu’il leur manque deux carac­té­ris­tiques clés qui font qu’une mon­naie est une mon­naie,» a affir­mé Paul Dono­van. « Une mon­naie doit pou­voir être uti­li­sée comme un moyen d’échange. Les cryp­­to-mon­­naies ne seront jamais capable de per­mettre cela. Un point c’est tout. » – « Le pro­blème fatal des cryp­­to-mon­­naies, c’est que leur offre ne peut qu’augmenter,» a-t-il expli­qué. « Il existe un poten­tiel d’augmentation illi­mi­té pour l’offre des cryp­­to-mon­­naies. »

Le Bitcoin constitue une illusion qui pourrait conquérir le monde” – The Atlantic | 10 624,75$

Derek Thomp­son : « It has not trans­for­med the eco­no­my of today. While the num­ber of bit­coin tran­sac­tions is gro­wing eve­ry year, it’s nothing close to a mass-mar­­ket consu­mer tech­no­lo­gy, like Google, or Net­flix, or even Pay­Pal. Bit­coin remains cum­ber­some to use (the typi­cal tran­sac­tion can take up to 10 minutes) and the price is extre­me­ly vola­tile. It is, for now, a frank­ly ter­rible cur­ren­cy built on top of a poten­tial trans­for­ma­tive tech­no­lo­gy. »

Voici ce qui pourrait provoquer l’éclatement de la bulle Bitcoin » – Bloomberg | 9 972,67 $

It’s been a puzzle to explain why bitcoin’s gone para­bo­lic. Why would we expect the way down to be any dif­ferent ? The prac­ti­cal appli­ca­tions for cryp­to­cur­ren­cies to faci­li­tate legal com­merce appear ham­pe­red by rela­ti­ve­ly expen­sive tran­sac­tion fees and the high ener­gy costs asso­cia­ted with mining at this junc­ture. On this note, Nobel Prize-win­­ning eco­no­mist Joseph Sti­glitz said that bit­coin “ought to be out­la­wed” because “it doesn’t serve any social­ly use­ful func­tion.” For­mer Fed Chair­man Alan Greens­pan has said that “you have to real­ly stretch your ima­gi­na­tion to infer what the intrin­sic value of bit­coin is,” cal­ling the cryp­to­cur­ren­cy a “bubble.” Per­haps it could end like the dot-com bubble — with inves­tors who have no clue how to value high-flying assets fleeing for the exit en masse.

Panneau de sortie” – Kunstler | 9 096,37 $

James Howard Kunst­ler : « I’m not so san­guine about Bitcoin’s sup­po­sed impre­gna­bi­li­ty, nor about many of its other appea­ling claims. The Mt. Gox affair of 2014 must be for­got­ten now, but back then some shar­pie hacked 850,000 Bit­coins (valued over $450,000,000) out of the exchange, which was pro­ces­sing almost two-thirds of all the Bit­coin trades in the world. Mt. Gox went out of busi­ness. Bit­coin tan­ked and then tra­ded side­ways for three years until (coin­ci­den­tal­ly?) the Gol­den Golem of Great­ness was elec­ted Lea­der of the Free World. Hmmmm…..  If Bit­coin were to keep rising to $1,000,000 per unit, as many inves­tors hope and pray, there wouldn’t be enough elec­tric power in the world to keep it going…. I’m not convin­ced that cryp­­to-cur­­ren­­cies are beyond the clutches of govern­ment, either. Around the world, in their cam­pai­gn to digi­tize all money, there must be a deep inter­est in either hiji­king exis­ting block-chains, or crea­ting offi­cial govern­ment Bit-monies to seal the deal of total control over finan­cial tran­sac­tions they seek…. My per­so­nal take on the phe­no­me­non is that it repre­sents the high point of tech­­no-nar­­cis­­sism — the idea that tech­no­lo­gy is now so magi­cal that it over-rides the laws of phy­sics. That, for me, would be the lou­dest “sell” signal. »

L’avis du Guardian au sujet des crypto-monnaies : la blockchain des imbéciles” – The Guardian | 8 196,15 $

The cor­res­pon­ding moment for the cryp­to­cur­ren­cy bubble will only be dis­cer­nible in retros­pect, but we have some pret­ty strong can­di­dates alrea­dy…. The notio­nal price of the main cryp­to­cur­ren­cies conti­nues to shoot upwards in a way that makes non­sense of the idea that they have any value as a medium of exchange. Even if they were wide­ly accep­ted by legal mer­chants, it would at the moment be luna­tic to exchange them for any­thing but real money. Bit­coin itself is tra­ding at more than $8,000, more than 10 times its price a year ago, and more than double what it was three months ago. Since it is only wide­ly used as a cur­ren­cy in drug deals or for ran­som pay­ments, there is either a huge boom in cri­mi­nal acti­vi­ties out­side the world of cryp­to­cur­ren­cies, or one within unre­gu­la­ted exchanges where these tokens are tra­ded.

Voici pourquoi le Bitcoin va emprunter la même route que celle des tulipes” – Financial Review | 7 058,75 $

Elmer Funke Kup­per : “At a more fun­da­men­tal level, we should won­der why Bit­coin exists at all. There is no rea­son. We can alrea­dy trade almost any­thing that is legal over the inter­net and pay for it in various ways. It’s fast, conve­nient, inex­pen­sive and quite safe.” “We can pre­dict the col­lapse of the value of Bit­coin, even when it may rise for a lit­tle while lon­ger. The intro­duc­tion of exchange-tra­­ded futures may signal the start of this pro­cess. Give it a year, maybe less. Bit­coin will become a case stu­dy for eco­no­mics stu­dents, tea­ching them about irra­tio­nal crowd beha­viour.” The back­bone tech­no­lo­gy is real and its value to consu­mers is real. And the­re­fore, it will sur­vive. Bit­coin as a digi­tal “cur­ren­cy”, won’t.

Kat­su­no­ri Sago : Bit­coin BTC=BTSP is in a bubble and its fair value should be around $100, or about 99 percent below the cur­rent level, Kat­su­no­ri Sago, chief invest­ment offi­cer of Japan Post Bank (7182.T) said on Thurs­day. Sago noted that blo­ck­chain is a great tech­no­lo­gy and one day bit­coin could become a major means of set­tle­ment. “But that will be years away, pos­si­bly more than a decade — so there’s no need to buy bit­coin now. Since no one knows when the bubble will burst, the best thing to do here is to stay away from it,” he said.

Le Bitcoin va prendre un chemin identique à celui de toutes les bulles de l’histoire” – Telegraph | 7 265,15 $

Tom Ste­ven­son : « I’m not even ter­ri­bly sure what bit­coin is : a cur­ren­cy or a com­mo­di­ty ? It sounds like the for­mer but it fails to exhi­bit the essen­tial cha­rac­te­ris­tics of money. It can hard­ly be vie­wed as a store of value. That requires at least a modi­cum of sta­bi­li­ty. Unlike the pound in my pocket, howe­ver, I can have no idea what a bit­coin will be worth tomor­row or in a year’s time. That, in turn, reduces its value as a unit of account. Why would ano­ther indi­vi­dual be pre­pa­red to accept my bit­coin for a good or ser­vice when its future value is so uncer­tain ; for the same rea­son, why would I want to spend my vola­tile bit­coin rather than hoard it in the hope of fur­ther appre­cia­tion. So bit­coin is a poor currency…..When it comes to bit­coin, people real­ly are buying it sole­ly because they expect other people to take it off them later for an even higher price. There is no bet­ter defi­ni­tion of the grea­ter fool theo­ry than this…. But I’m pre­pa­red to wait and see. I will not be ris­king my savings on what looks remar­ka­bly like the tulip mania of the 1630s… War­ren Buf­fett also famous­ly war­ned against inves­ting in busi­nesses you can­not unders­tand. If ever there were an invest­ment that fits this des­crip­tion, bit­coin is sur­ely it….  While bit­coin is soa­ring, the grea­ter fools look like those of us refu­sing to fol­low the siren calls of the lat­­ter-day shoe­shine boys. Like Joe Ken­ne­dy, howe­ver, I’m pret­ty relaxed about who will have the last laugh. What goes up like a rocket comes down like a stick. »

Robert Schil­ler : « Bit­coin is a fad, just like bime­tal­lism before it, accor­ding to one Nobel Prize-win­­ning eco­no­mist. The obser­va­tion came from Ame­ri­can eco­no­mist Robert Shil­ler, who com­pa­red the cryp­to­cur­ren­cy to the bime­tal­lism fad of the late 19th cen­tu­ry when both gold and sil­ver were accep­ted as legal ten­der. »

Peter Schiff : « I believe it’s not going to suc­ceed in deli­ve­ring the mone­ta­ry uti­li­ty that people [expect],” Schiff said. “I do not think it’s going to be the money of the future. I think it’s the bubble of the present.”  “I think a lot of people unfor­tu­na­te­ly, have attri­bu­ted pro­per­ties to Bit­coin and other cryp­to­cur­ren­cies that do not exist,” he said. “I think that people who are right­ful­ly skep­ti­cal of the dol­lar, the euro, the yen are taking refuge in bit­coin or other cryp­to­cur­ren­cies and they’ve jum­ped from the frying pan into the fire.”

Jamie Dimon affirme que si vous êtes suffisamment “stupide” pour acheter des Bitcoins, vous en paierez un jour le prix” – CNBC | 5 128,05 $

I could care less about bit­coin…. I don’t per­so­nal­ly unders­tand the value of some­thing that has no actual value. You all can do wha­te­ver you want and I don’t care….. If you’re stu­pid enough to buy it, you’ll pay the price for it one day. I’ve also told people that it can trade at $100,000 before it trades to zero. The only value of bit­coin is what the other guy’ll pay for it. Who cares about bit­coin ? The world economy’s so big, JPMor­gan alone, $6 tril­lion, we move all this money, and bit­coin in total, all these cur­ren­cies, $50 bil­lion dol­lars, maybe a bil­lion dol­lars trades a day. The other thing I’ve always [said]about bit­coin, govern­ments — and this is not a tech­no­lo­gi­cal sta­te­ment — govern­ments are going to crush it one day.”

Richard Har­ris : « It is a fea­ture of all bubbles dri­ven by the herd to find that many wise, high pro­file and ana­ly­ti­cal finan­cial obser­vers are their most ardent sup­por­ters. The rest of the crowd are blin­ded by greed or grip­ped by the fear of mis­sing out. So it is with bit­coin. ….The fatal aspect lacking from cryp­to­cur­ren­cies is the backing of a cen­tral bank, which has all of the eco­no­mic, mili­ta­ry and intel­lec­tual resources of a nation to sup­port it. … Cryp­to­cur­ren­cies are going up because they are going up ; they are the Kar­da­shians of the finan­cial world ; famous for being famous. But fame does not last fore­ver, nor do mar­ket manias.

Bit­coin has abso­lu­te­ly no value now, and it’s going to cost people a lot of money. Okay, it’s gone from 4,700 to 3,500 in a week, and it’s going to go from 3,500 to zero. Now, it might go from 3,500 to 10,000 first, but it’s going to end up being zero. Bit­coin is a pseu­do­cur­ren­cy. It’s no more sui­table as money than salt or big round rocks.

James Mac­kin­tosh : « Behind eve­ry bubble is a good idea burs­ting to get out, and bit­coin kind of looks like a good idea, at least if you squint a bit. A digi­tal cur­ren­cy without bor­ders that govern­ments can’t control and that allows secret online tran­sac­tions ? I’m in. Bit­coin itself ? Not so much. So is a single bit­coin worth $500,000, $5,000, $500 or $0 ? I’m incli­ned to say $0, espe­cial­ly if bitcoin’s value depends on it being adop­ted as a glo­bal digi­tal cur­ren­cy to replace dol­lars. There is no chance what­soe­ver that bit­coin can dis­place the dol­lar, for the simple rea­son that it is bad­ly desi­gned. Bit­coin can handle a pathe­ti­cal­ly small num­ber of tran­sac­tions, and uses an inor­di­nate amount of elec­tri­ci­ty to do so, making it enti­re­ly unsui­table to replace ordi­na­ry money. »

Le Bitcoin, l’Ether et les autres crypto-monnaies pourraient être en train d’assister au début de la fin – MarketWatch | 4 669,66 $

Brett Arends : « The sud­den Chi­nese cra­ck­down on the vir­tual coin fun­drai­sing of bit­coin and other cryp­to­cur­ren­cies that cau­sed the plunge is either the end of the begin­ning for the cryp­­to-par­­ty — or, more like­ly, the begin­ning of the end…. It makes no serious sense. In other words, cryp­to­cur­ren­cies lack pre­ci­se­ly the sup­po­sed unli­mi­ted upside that spe­cu­la­tors dream about. The only way we are ever loo­king at so-cal­­led “blue sky” valua­tions is if the govern­ments of the world all lose their col­lec­tive minds… And as for those cryp­to­cur­ren­cy fans and their liber­ta­rian fan­ta­sies : If you think bit­coin or Ether or wha­te­ver is some­how beyond govern­ment control because it is so decen­tra­li­zed across so many dif­ferent com­pu­ters, think again. Govern­ments may not be able to shut down all the ser­vers, but they don’t have to. They can in theo­ry ban people and com­pa­nies under their juris­dic­tion from buying, sel­ling, tra­ding, or hol­ding these things. Govern­ments can make your cryp­to­cur­ren­cies uncon­ver­tible into any­thing use­ful… Cryp­­to-mania may conti­nue for now. Tra­ders will be wat­ching the charts to see how the trends deve­lop. But the long-term invest­ment sto­ry looks like ano­ther mat­ter. The risks are rising. »

Nothing has chan­ged, bit­coin is still a spe­cu­la­tive bubble. The price, in my view, will even­tual­ly go to zero. But of course, on its way there, it might first go to more ridi­cu­lous highs. A higher price does not mean that it is not a bubble. It just means that the bubble is get­ting big­ger. So, for what it is worth, be war­ned. If you have invest­ments in cryp­to cur­ren­cies, you are inves­ted in a Pon­zi scheme. At the end of this, for eve­ry win­ner, there will have to be the same amount of losers.
