Cryptocurrencies are having a moment. You’ve probably heard a thing or two about Bitcoin and Ethereum. Namely, their prices seem to be skyrocketing (or plummeting, depending on the day). There’s more to the story, and as the investing cliche goes: don’t buy what you don’t know. So let’s find out more.

What Is Cryptocurrency?

Cryptography has to do with coding to keep data secure, and cryptocurrency is a digital or virtual asset that uses cryptography as a security measure. For that reason, it’s hard to counterfeit. Bitcoin is one of the first cryptocurrencies to hit the scene. It was launched in 2009 by “Satoshi Nakamoto,” a pseudonym that could be a person or a group (it was open source and peer to peer). The thing is, there’s no central agency (like the government) that issues or regulates these cryptocurrencies.

Which is why it’s been such an attractive option for shady business activities, like money laundering. You can buy and sell it just like any other investment, from company stock to Beanie Babies. But while companies have IPOs, or initial public offerings, cryptocurrencies have ICOs, initial coin offerings, and any entity can launch it as an investment. The Atlantic illustrates the problem with not having a central authority regulating these currencies:

“Last month, the technology developer Gnosis sold $12.5 million worth of ‘GNO,’ its in-house digital currency, in 12 minutes. The April 24 sale, intended to fund development of an advanced prediction market, got admiring coverage from Forbes and The Wall Street Journal. On the same day, in an exurb of Mumbai, a company called OneCoin was in the midst of a sales pitch for its own digital currency when financial enforcement officers raided the meeting, jailing 18 OneCoin representatives and ultimately seizing more than $2 million in investor funds. Multiple national authorities have now described OneCoin, which pitched itself as the next Bitcoin, as a Ponzi scheme; by the time of the Mumbai bust, it had already moved at least $350 million in allegedly scammed funds…”
As they put it, “ICOs are catnip for scammers” because there are no checks and balances the way there are with IPOs. So if you’re going to invest in a coin, which is an iffy enough move as it is, you certainly want to make sure it’s not just any random cryptocurrency that could just be a scam.

So what about tokens like Bitcoin or Ethereum, which are popular, widely covered options? (And that are actually used as currency.) Are they smart investments?

Is Cryptocurrency a Good Investment?

Some people say investing is like playing the lottery. That’s not entirely accurate, though. Long-term, broad investing, the kind of investing we’ve advocated here and the kind that will help you build a nest egg over time, is very different from speculative, active trading, which is a lot more like gambling. Cryptocurrency, a volatile, unpredictable investment, falls into that category.

With active trading, you’re taking a guess at how a specific investment (or investments) will trade on a short-term basis. The goal isn’t to simply keep up with the stock market like it is with long-term investing; the goal is to make a bunch of money and get rich quickly. And you know, some Bitcoin and Ethereum investors did get rich quickly! Seems like a good deal, right? But the thing is, the price of these cryptocurrencies often swings from one extreme to another. (In one day in June, the price of Ethereum plummeted from $319 to $0.10!)

Plus, any time the value of something skyrockets too quickly, a bubble often follows, and that’s exactly what Forbes contributor Clem Chambers predicts:

“Cryptocurrencies, of which bitcoin is the leader, will fall back in value and more than the fat drop bitcoin has already had.”
