The Honest Case Against Bitcoin

A case you only ever hear defended is a case you cannot trust. So here we do the opposite of a sales pitch: we lay out the strongest objections to Bitcoin as fairly as a critic would, and only then give the considered response. Where an objection lands, we say so. If you finish this article more skeptical, the framework is doing its job.

1. It is too volatile to be money

The objection. Money is supposed to be a stable store of value and unit of account. Bitcoin's price can swing 10% in a day and lose half its value in months. No one prices a coffee in something that unstable, and no one wants their savings to do that. As money, it fails the very job it claims to do best.

The response. This objection is largely correct about the present, and pretending otherwise would be dishonest. The fairest counter is about trajectory, not denial: Bitcoin is young and still being adopted, and a new monetary asset being volatile while the market discovers its value is expected, not surprising. Its volatility has trended down over its lifetime as it has grown. Whether it keeps falling enough to make Bitcoin a usable everyday unit of account is genuinely unknown — and anyone who tells you the answer with certainty is guessing.

2. Nobody actually spends it

The objection. Real money circulates. Bitcoin is mostly held and traded, not spent on goods. If it is not used as a medium of exchange, calling it money is wishful thinking — it behaves like a speculative asset, not a currency.

The response. Two honest points. First, an asset can mature into money store-of-value first, medium-of-exchange later; gold became a store of value long before coins circulated. Many supporters argue Bitcoin is simply early in that sequence. Second, the spending problem is partly technical and is being addressed — the next article covers the Lightning Network in detail. That said, the objection has force today: as a day-to-day medium of exchange, Bitcoin is not there yet, and the volatility above is a big reason why.

3. It wastes enormous amounts of energy

The objection. Bitcoin mining consumes electricity on the scale of a small country, much of it from fossil fuels, at a time when the world is trying to cut emissions. Whatever its monetary properties, that environmental cost is hard to justify for a system that processes relatively few transactions.

The response. The energy use is real and large; that is not in dispute. The disagreement is over whether it is wasteful. As we saw, the energy is not a side effect — it is the security, the wall that makes the ledger expensive to attack. Defenders add that a meaningful and growing share of mining uses stranded, surplus, or renewable energy (miners chase the cheapest power, which is often otherwise-wasted energy), and ask that the cost be weighed against the energy footprint of the entire traditional banking and gold-mining systems it might partly replace. Critics reply that this is still a large cost for a young system, and that comparison is not exoneration. This one comes down to how you value what the energy buys.

The strongest objections to Bitcoin are not myths to be swatted away. They are real costs to be weighed.

4. It cannot scale

The objection. The base Bitcoin network handles only a handful of transactions per second — nowhere near the thousands that global payment networks process. It can never serve billions of people directly, so it cannot become world money.

The response. This is true of the base layer by design — keeping it small and verifiable on modest hardware is part of what keeps it decentralized. The intended answer is layering: settle large, final transactions on the base chain and push everyday payments to faster layers built on top, much as the traditional system settles between banks in bulk while you tap a card instantly. The Lightning Network is the leading example. Whether layered scaling can work smoothly at global scale is still being proven, so this is a reasonable open question rather than a settled win for either side.

5. Governments can crush it

The objection. Bitcoin exists at the pleasure of regulators. Governments can ban it, choke the exchanges where people buy and sell, and prosecute businesses that accept it. A money that authorities can strangle is not the independent money its supporters imagine.

The response. The network itself has proven very hard to stop — it has no head office to raid, and attempts to ban it have pushed activity elsewhere rather than ending it. But the objection lands on the edges: the on- and off-ramps between Bitcoin and traditional money are regulated choke points, and aggressive regulation can sharply limit access for ordinary people even if it cannot kill the protocol. Censorship-resistance is real at the core and weaker at the boundary. Honest supporters concede the boundary is a genuine vulnerability.
