Chapter: 7
Up to this point in Reichental’s book, the focus has been on coins: bitcoin, ether, altcoins with their own blockchains. Chapter 7 shifts to tokens, and honestly, this is where crypto gets interesting and confusing at the same time.
Tokens are where NFTs live. Where ICO scams happened. Where fractional real estate ownership becomes possible. If coins are digital money, tokens are digital stand-ins for almost anything else.
What is a token?
A token is a stand-in for something of value. Arcade tokens. Subway tokens. A restaurant coupon for two entrees for the price of one. A winning lottery ticket.
In crypto, tokenization turns real-world or digital assets into blockchain entries that are easier to trade and transfer.
Tokens vs. coins: the difference that matters
This trips up almost everyone, including me the first time through.
Coins (bitcoin, ether) are digital money on their own dedicated blockchains. They function like cash.
Tokens represent assets you can buy. They are not money themselves. They are tickets, shares, access passes, or certificates. Built on top of smart-contract blockchains like Ethereum, not on their own chains.
Other differences:
- Creating a coin means building a new blockchain. Hard.
- Creating a token means deploying a smart contract on an existing chain. Much easier.
- Tokens power dapps. Ethereum’s Basic Attention Token (BAT) lets advertisers pay publishers directly.
Think of it this way: ether is the currency. A token on Ethereum is a gift card, a stock certificate, or a concert ticket, depending on what it represents.
Fungible vs. non-fungible
Fungible means interchangeable. Your $20 bill equals my $20 bill. One bitcoin equals any other bitcoin. One ounce of gold equals another ounce.
Non-fungible means unique. Two houses with the same floor plan on the same street are not worth the same if one has a mountain view and the other faces a parking lot. A Picasso is not interchangeable with a painting from a talented amateur.
Crypto tokens split along this line.
Four types of fungible tokens
Security tokens represent ownership in real assets: real estate, cars, company stock. A token for 5% of a private jet is fungible with another 5% stake.
Utility tokens grant access to a product or service. A gaming company issues in-game currency tokens. Airline miles are the real-world version: valuable inside one ecosystem, useless at a competitor.
Governance tokens give voting rights on decentralized protocols. Hold tokens, vote on changes. Used heavily in DeFi and DAOs.
Transactional tokens track commerce within an industry. A shipping company logging international trade on a blockchain.
ICOs: the fundraising wild west
Initial Coin Offerings (ICOs) let crypto startups raise money by selling utility tokens. Ethereum’s 2014 ICO raised $18 million in 42 days. Early investors made fortunes.
The problem: no SEC regulation. Scammers loved it. A 2017 study found up to 80% of ICOs that year were scams. Dollar losses from scams ($1.34 billion) were still smaller than legitimate ICO investment ($11 billion), but that is cold comfort if you were in the 80%.
The SEC eventually applied the Howey test (from a 1946 Supreme Court case about citrus groves). If an offering involves investing money, expecting profit, from others’ efforts, it is a security. Most “utility tokens” failed that test. ICOs mostly died.
Security Token Offerings (STOs) emerged in 2018 as the regulated alternative. STOs follow SEC rules. More expensive and complex than ICOs, but actually legal.
NFTs: owning the certificate, not the thing
Non-fungible tokens (NFTs) exploded in the late 2010s. Each one is unique. Digital art, sports memorabilia, virtual real estate, in-game weapons.
The first big hit was CryptoKitties in 2017. Collect and breed digital cats on Ethereum. It nearly clogged the entire network.
Here is the part people miss: buying an NFT usually means you own a certificate of authenticity on the blockchain, not the underlying image or file. Anyone can screenshot the art. You own the verified instance with a unique signature.
Is that valuable? Collectors of signed baseball cards would say yes. Critics call it a bubble built on hype. Both sides have a point.
Gaming tokens are a fast-growing NFT category. Weapons, costumes, skills your avatar actually owns, not the game company. Some include governance rights too.
Ethereum token standards
Most tokenization runs on Ethereum:
- ERC-20: Rules for fungible tokens. Transfer between accounts, check balances. BNB started here before moving to its own chain.
- ERC-721: The NFT standard. Transfer unique tokens, check ownership, total supply.
- ERC-1155: Handles both fungible and non-fungible in one standard. May replace ERC-20 and ERC-721 over time.
Solana and other chains mint NFTs too. But Ethereum’s maturity keeps it dominant for now.
Real estate tokenization
This example hit home. Alan Forrest, the high schooler in the book, cannot afford a whole property. But he could buy tokens representing a 5% share of an apartment building and collect 5% of rental income.
Even 5% was too much for Alan. His parents Peter and Lynn tried it instead. They bought 10% of a fourplex and started receiving passive rental income. Lower legal costs. Lower barrier to entry. Blockchain handles the fractional ownership.
That is tokenization doing something useful, not just selling JPEGs of apes.
Tokenomics: the economics behind the hype
Tokenomics blends “token” and “economics.” It covers everything that makes a crypto asset valuable or worthless:
- How many tokens exist?
- How are they created or distributed?
- What can you use them for?
- Who controls supply?
Central banks used to be the only ones setting monetary policy. Now every project designs its own. Perception matters as much as math. Before buying any token, read the tokenomics first.
Risks and the road ahead
Tokens are early. Some experiments will win. Many will fail.
Security tokens offer a regulated fundraising path. Fractional ownership of real assets is genuinely useful. NFTs are the most debated: scammy bubble or new asset class that finally pays digital creators?
NFTs are creeping into DeFi too. Used as loan collateral, in staking pools, for governance. That is more interesting than profile picture collections.
The risk nobody talks about enough: if the blockchain your NFT lives on dies, your NFT might die with it. Ethereum looks stable. Smaller chains do not.
What I think after reading this chapter
Coins got crypto on the map. Tokens are where the actual building happens. Utility tokens, governance tokens, fractional real estate, NFTs for creators. The use cases are real even when the hype is not.
The ICO era was a mess, and the SEC crackdown was overdue. STOs and security tokens are the grown-up version of that fundraising model.
NFTs? I am still skeptical of most art NFTs as investments. But the underlying tech (provable ownership of digital assets) is not going away. Gaming, real estate, and DeFi are better applications than cartoon profile pictures.
If you remember one thing: coins are money, tokens are everything else. And “everything else” is where crypto gets both exciting and dangerous.
