How do I buy cryptocurrency?

While some cryptocurrencies, including Bitcoin, are available for purchase with U.S. dollars, others require that you pay with bitcoins or another cryptocurrency.

To buy cryptocurrencies, you’ll need a “wallet,” an online app that can hold your currency. Generally, you create an account on an exchange, and then you can transfer real money to buy cryptocurrencies such as Bitcoin or Ethereum.

What is Cryptocurrency?

Cryptocurrency is a form of payment that can be exchanged online for goods and services. Many companies have issued their own currencies, often called tokens, and these can be traded specifically for the good or service that the company provides. Think of them as you would arcade tokens or casino chips. You’ll need to exchange real currency for the cryptocurrency to access the good or service.

Some of the reasons:

  • Some see cryptocurrencies such as Bitcoin as the currency of the future and are racing to buy them now, presumably before they become more valuable
  • Some like the fact that cryptocurrency removes central banks from managing the money supply since over time these banks tend to reduce the value of money via inflation
  • Some like the technology behind cryptocurrencies, the blockchain, because it’s a decentralized processing and recording system and can be more secure than traditional payment systems
  • Some see them going up in value and have no interest in the currencies’ long-term acceptance as a way to move money

Should you buy cryptocurrency?

Cryptocurrency is an incredibly speculative and volatile buy. Stock trading of established companies is generally less risky than investing in cryptocurrencies such as Bitcoin.

Cryptocurrencies may go up in value, but many investors see them as mere speculations, not real investments. The reason? Just like real currencies, cryptocurrencies generate no cash flow, so for you to profit, someone has to pay more for the currency than you did.

Cryptocurrency needs stability and Bitcoins price volatility creates a conundrum.

If bitcoins might be worth a lot more in the future, people are less likely to spend and circulate them today, making them less viable as a currency. Why spend a bitcoin when it could be worth three times the value next year?

ANXIETY AND ITS EFFECTS.

Anxiety is your body’s natural response to stress. It’s a feeling of fear or apprehension about what’s to come. The first day of school, going to a job interview, or giving a speech may cause most people to feel fearful and nervous.

In the case of an anxiety disorder, the feeling of fear may be with you all the time. It is intense and sometimes debilitating.

This type of anxiety may cause you to stop doing things you enjoy. In extreme cases, it may prevent you from entering an elevator, crossing the street, or even leaving your home. If left untreated, the anxiety will keep getting worse.

Anxiety disorders are the most common form of emotional disorder and can affect anyone at any age. According to the American Psychiatric Association , women are more likely than men to be diagnosed with an anxiety disorder.

Therapist Heidi McBain tells Bustle that a variety of therapy sessions are particularly likely to cause "hangovers" afterwards. "Therapy hangovers often happen after a deeply emotional session," she says. "This can be the result of talking about something that feels very vulnerable to you. It can also be grieving the loss of someone or something close to you in your life. It can be coming to a hard realization of some changes that you want/need to make in your life."

It's also a scientifically proven phenomenon. Researchers at NYU found in a 2016 study that emotional brain-states after intense experiences can persist for long periods of time, which is why you don't just leave your emotions in the space of therapy; you carry them with you afterwards. The hangover lasts for as long as your brain requires to process emotional information — which, in therapy, is often related to your memories. Raking through your past and making big emotional discoveries, even in a safe, therapeutic environment, has a cost.

The therapy hangover isn't a signal you should stop therapy. In fact, it's a sign that you should keep going — and the rewards of going through the pain are worth it for the emotional clarity you get on the other side.
