The crypto world is buzzing. If you ask a true believer, they’ll say this is just the beginning. Ask a skeptic, and they’ll swear we’re watching a bubble inflate in real time. One that could pop any second.

I saw the excitement firsthand at a crypto event in Brooklyn last week. The bar was packed. People were animated. It felt like a flashback to 2020 and 2021, when crypto fever gripped everyone from twenty-something retail traders to grandparents. Back then, it was all about Bitcoin, flashy NFTs like the Bored Ape Yacht Club, and anything promising wild returns. It was a digital casino where everyone hoped to strike it rich. Fast.

But then came the crash. The “crypto winter” arrived, marked by the spectacular downfall of crypto exchange FTX and its poster boy Sam Bankman-Fried. Billions vanished. Trust collapsed. Regulators circled.

Now? The energy is back. And it’s confusing.

At the Brooklyn event, hosted by Wire Network (a startup trying to connect different crypto systems, or “blockchains”), the optimism was palpable. “There’s never been a better time to be a crypto developer,” co-founder Ken DiCross told me.

On paper, crypto’s comeback looks unstoppable. The industry’s total market value has ballooned by over $3 trillion since the start of 2023. Companies like Robinhood, Coinbase, and MicroStrategy are riding the wave. Circle Internet Group, the firm behind one of the biggest “stablecoins,” went public in June at a $6 billion valuation. It shot up to nearly $50 billion in just weeks.

Wait, what’s a stablecoin?

A stablecoin is a type of cryptocurrency designed to hold a steady value, usually pegged to something like the U.S. dollar. The idea is to give people the speed and flexibility of crypto without the wild price swings of Bitcoin or Ethereum. In theory, you could use stablecoins instead of cash to buy your coffee or pay your rent. In reality, we’re not there yet.

But the bet from crypto firms is clear: one day, we’ll all use digital dollars instead of paper ones. That’s what’s driving today’s gold rush. The question is: Are people getting ahead of themselves?

The new crypto darlings: DeFi and Bitcoin treasury companies

Much of the current hype centers on DeFi, short for decentralized finance. Think of it as an attempt to rebuild Wall Street without the banks. Instead of a bank approving your loan or handling your trades, code does it. No middlemen, no gatekeepers. Sounds revolutionary, but so far, it’s mostly been a playground for speculators and tech geeks.

Then there are the Bitcoin treasury companies. These are regular businesses that are loading up their balance sheets with Bitcoin instead of dollars, euros, or gold. MicroStrategy is the poster child, spending billions to buy Bitcoin and turning itself from a sleepy software company into a kind of crypto hedge fund. The idea is that Bitcoin will outpace inflation and fiat currencies over the long run.

Bubble or boom?

There’s no clear answer. The numbers are dizzying. The hype is real. And yet, there’s still so much uncertainty about whether crypto’s grand promises will ever match reality. Even with a crypto-friendly president in the White House, the road to replacing cash or Wall Street is long.

So, is this a bubble? Maybe. Maybe not. It depends on who you ask.
