Bitcoin crossed the $10,000 milestone on Tuesday night, so far defying expectations from financial experts that the cryptocurrency would crash.

Bitcoin, a form of crypto and digital currency, has seen its value bounce from $1,000 per bitcoin in the beginning of the year to $10,000 for one bitcoin on Tuesday.

The value of all purchased bitcoins in existence is close to $167 billion, according to BBC.

But should you believe in the bitcoin hype? Experts worry about a market drop. Bitcoin is nearing $11,000, despite increased warnings that the currency is trapped in a bubble, Bloomberg reported.

This is going to be the biggest bubble of our lifetimes, hedge fund manager Mike Novogratz said on Tuesday, according to Bloomberg.

Novogratz, who invested in bitcoin when it cost $90, said he has started a $500 million fund because of the currencys ability to transform the market.

Experts worry that bitcoin will soon be regulated, which could drop its value, too.

Its extremely difficult to determine a fair value for bitcoin, said Craig Erlam, senior market analyst in London at Oanda, to Bloomberg. And theres no news of substance on the regulatory front.

And bitcoin has shown roller coaster behavior, according to Quartz. For example, stocks during the 2008 financial crisis dropped 40 percent. Bitcoin sees double-digit drops all the time. Thats one reason Wall Street has been cautious to embrace it.

However, some experts believe the asset will continue to grow. CNBC's Jim Cramer said in June digital currency could help ward off cyberattacks.

"I think it could because the European banks are frantically trying to buy them so they can pay off ransomware. It's a short-term way to be able to deal with cybersecurity. It is the way to pay off the bad guys," Cramer said on "Squawk on the Street."

Though markets are cautious to fully embrace it, Wall Street strategist Tom Lee told CNBC this week that bitcoin could be a new form of gold for the younger generation.

In fact, a young couple from Provo said in 2013 that they planned to document their first 90 days as a married couple living on the virtual currency. They planned to use bitcoin to purchase "furniture, rent, groceries, travel, gas, restaurants and even medical expenses," according to the Deseret News.

Bitcoin offers digital trust, which is sitting well with those who worry about institutional banking.

The cryptocurrency was introduced on the internet in 2009. Bitcoins are kept in an online wallet. There's no card or cash that represents bitcoin. All exchanges are done through the internet.

As ABC News reported, bitcoin was created as an alternative to modern currency. "Transactions allow anonymity, which has made it popular with people who want to keep their financial activity, and their identities, private."

In a way, bitcoin has become more of a replacement for gold, Lee told CNBC.

"It's valued as if it is a small company today," Lee told CNBC. "We think over the next 10 years, this new generation of millennials are going to view trust as a replacement for gold. So, bitcoin is essentially digital gold for another generation."

Lee said earlier this year he expects bitcoin to be valued at $11,500 in 2018.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
