“Veneno de ratas al cuadrado”; “ojalá nunca se hubieran inventado”, “el traje nuevo del emperador” o “un imán para imbéciles”... Estas andanadas sobre bitcoin y las criptodivisas no las han dicho un puñado de haters de bitcoin en las redes sociales, sino cuatro de las personalidades más seguidas en el mundo financiero: Charlie Munger, Warren Buffett o Jeremy Grantham o Nicholas Nassim Taleb.

The most recent has been that of the latter, the writer of Lebanese origin, author of great success books in the financial field such as antifragil or the black swan.He stayed comfortable in a thread that tweeted as he pedaling on the static bike, as confessed in another trill.

"Bitcoin is like a contagious disease.It expands, expands and its price triggers to saturation, that is, until all those so fools to buy history are invested.This is the maximum fragility ".In his opinion, "it is not a currency, nor a refuge of value, nor a coverage against inflation, nor a protection against government tyranny or catastrophes, but a fragile bubble"

"It has no value, only speculation"

His download has been the last, but despite its hardness it would not be the fiercest.Or, at least, it would be at the height of those who have poured two of the best investors in history, Warren Buffett and his partner Charlie Muger.The latter said in an interview when Bitcoin traded at 100 dollars that Critptomoneda was "rats poison".Time later, when the price already touched the 10.000 dollars, his friend Buffett was asked and he still went further: "It is now the square of rats square".

That, although Warren Buffett recognizes that blockchain technology in which crypts are sustained is "important".What do you not like, then?Buffett, on the one hand, that “has no unique value at all, does not produce anything.It is bought just because the group of people who want to sell it is expected to grow ”.

Pure speculation about a complex concept, which is feeded in the price bundle phases."When there are price increases in something you do not understand, you get much more excited than if they occur in something you understand," explained the legendary investor to the CNBC.

Dark uses and electricity spending

His friend Muger is still more critical."I'm never going to buy a cryptocurrency.I hope they would never have invented.It's artificial gold without any value, "he said at an annual Berkshire Hathaway conference.In fact, he even considers "immoral" to invest in this asset, among other things, for the relationship that is attributed to the crypto world with the money laundering for the anonymity of operations.

Although at this point, it could also be argued that the dollar has historically been the reference currency for drug trafficking and other dark businesses.And that does not turn the green ticket into an illicit currency, but the use that people make of these media.

What do the defenders of the crypto world of this negative vision of these two major investors say?"They do not understand technology and, if they do not understand technology, we cannot pretend that they understand Bitcoin," he said in a Finect streaming about investment in crypts Eneko Knörr, the inverter in Spanish start ups that has "about half"Your portfolio in crypts."Buffet has acknowledged that he was wrong not contributing to Google and Amazon, he saw them pass by but did not invest because he didn't see it.".

The other point that Bitcoin Enarbolan skeptics is the amount of energy spent with crypts.Among them, Bill Gates, who remembers that "uses more electricity by transaction than any other means known in humanity, so it is not good for the environment" and that is why he affirms that he does not invest in Bitcoin.

Now, there are also personalities from the financial world who defend them.Maybe Bill Miller is his greatest exponent. Este gestor, que se hizo famoso por batir con su fondo al S&P 500 durante 15 años consecutivos, fue construyendo su posición en criptos hasta llegar al 50% de su cartera personal.

Caution in such volatile assets

At the moment, it has been wonderful, as happened during that period of 15 years investing in shares.Although it should be remembered that Miller ended up leaving his fund for the important losses he suffered during the subrprime crisis, when he entered the real estate sector before Lehman Brothers's fall, thinking that he would be rescued as he had already happened with Bear Stear Stear.

The battle between fans and detractors is served.And more with the volatility of these cryptoactives.Critics emphasize 50% that Bitcoin and their fellow men have lived in just two months.Supporters, in the impressive bullish rally of recent years.

You are on the side you are, the advisors always recommend having a very reduced exposure to assets that have such wild volatility.And that the investment is always with money that will not be needed in the short or medium term.
