It should be obvious by now: JPMorgan Chase & Co. (NYSE: JPM) CEO Jamie Dimon hates Bitcoin.
The leader of America's biggest bank - arguably the most influential person on Wall Street - has hurled insults at Bitcoin twice in the past month. Those comments have contributed to Bitcoin price volatility in recent weeks.
At a Sept. 12 investors' conference, Dimon called Bitcoin a "fraud." And he was just getting started...
"It's just not a real thing, eventually it will be closed," Dimon said, somehow oblivious to the fact that, as a decentralized network spread across the globe, Bitcoin cannot be "closed."

"It's worse than tulip bulbs. It won't end well. Someone is going to get killed," Dimon ranted. The reference to the Dutch Tulip Mania of the 1600s was his attempt to delegitimize Bitcoin's phenomenal price gains - 500% in the last 12 months - as a dangerous bubble.
For good measure, Dimon vowed to "fire in a second" any JPMorgan employee found to be investing in Bitcoin.
"It's against our rules, and they are stupid," he said. "And both are dangerous. The currency isn't going to work. You can't have a business where people can invent a currency out of thin air and think that people who are buying it are really smart."
"As you would expect from a Wall Street bankster, Dimon has his own selfish interests at heart..."
Then, last week, Dimon went on the attack again in an interview with CNBC TV18 in India.
"It's creating something out of nothing that to me is worth nothing," he said of cryptocurrencies, deriding the asset class as a "novelty."

Dimon then warned that governments would not allow Bitcoin and other cryptocurrencies to continue to grow and gain traction.
"The bigger they get, the more governments are going to close them down," he said.
As an organization that understands the potential of cryptocurrencies to reinvent the financial sector, we here at Money Morning couldn't disagree more with Dimon.
But the more interesting question is why someone in Dimon's position is bothering to go after Bitcoin at all.
As you would expect from a Wall Street bankster, Dimon has his own selfish interests at heart...
Why Jamie Dimon Keeps Attacking Bitcoin
In a nutshell, Jamie Dimon is terrified of Bitcoin and the entire cryptocurrency phenomenon.
He should be. Bitcoin was designed from the outset to be a system that would allow individuals to conduct transactions outside of the traditional banking system.
In short, Bitcoin is designed to make banks like JPMorgan Chase obsolete.
Just as scary to a banker like Dimon is that the Bitcoin network is controlled solely by code, not a central bank or government. And it's no accident that Bitcoin appeared in the wake of the 2008 financial crisis.
In public comments made shortly after he launched Bitcoin in 2009, creator Satoshi Nakamoto called out central banks for debasing fiat currencies and traditional banks for lending out money "in waves of credit bubbles with barely a fraction in reserve."

Dimon has understood Bitcoin's potential to disrupt Wall Street at least since 2014, when it first became clear the digital currency was on his radar.
"When I go to Silicon Valley... they all want to eat our lunch. Every single one of them is going to try," Dimon told a gathering of JPMorgan investors in February 2014.
He repeated the sentiment in April 2015 in his annual letter to shareholders, this time mentioning Bitcoin by name. Dimon said "there is much for us to learn" from faster, cheaper, and more secure payment systems like Bitcoin.
Imagine Dimon's alarm this year as the price of Bitcoin soared from $968.23 to $5,000, while other cryptocurrencies, via a wave of initial coin offerings, sprang up like weeds in springtime.
Dimon is using his considerable clout to try to undermine cryptocurrencies before they get any more powerful.
And he's not the only Wall Street heavyweight speaking out against Bitcoin...

I love having information about stocks as a compliment to a good cup of coffee.
All these bankers talking against Bitcoin and the other cryptocurrency's it is because they are worried that the bank's will lose all that money on transactions its all about money don't pay no attention to these greedy bankers only out for there own interest.
Bitcoin is a joke, an version of the barter system with an entirely subjective value and nothing of substance to back it up financially. Say what you want about the U.S. dollar, but it has the full backing of the federal government. Where does Bitcoin's full backing come from? I wouldn't invest a dime in Bitcoin any more than I'd "invest" in tomatoes from my neighbor's backyard.
People borrow to invest in Cryptocurrency.. All this free credit being used to push up the price its a bubble. But its fun. People keep saying it can't fail.. But no-one knows how to properly explain how it works. They use fancy words yes. they say the lingo. But none of it is really real. Its the words of a con-artist.
You are an idiot Bruce. Even your grammar is incorrect. The dollar is not back by anything and can be manipulated by printing more dollars. Big banks are trashing Bitcoin because it's their direct competitor. Wake up….
