Blockstream chief executive Adam Back says efficient markets are finally pricing memecoins, smart contract tokens and other "air tokens" toward zero.
Adam Back Repeats His Bitcoin Recommendation
Back, the inventor of Hashcash and one of Bitcoin's most outspoken maximalists, made his case in posts shared on X across May 23 and 24. He told followers to "buy bitcoin, hodl, repeat," and said he expected the efficient market hypothesis to value alternative coins near zero. His only surprise, he noted, is how long the repricing took to arrive.
His argument rests on three absences.
The tokens he targets produce no cash flows for holders and draw no meaningful blockspace demand, and they hold no durable advantage over rivals.
Without any of those traits, Back contends, there is no rational basis for a price above zero. He has made the same call since the previous market cycle.
Bitcoin (BTC) gives that view some recent backing. The asset slid to a four-week low after a delayed Clarity Act vote, then rebounded sharply once a broad macro rally took hold, while most altcoins failed to hold any gains from the same catalyst.

Why the Air Token Argument Matters
Back's diagnosis leads to a single prescription. If most tokens trade above their fundamental value, he reasons, Bitcoin stands apart as the only asset he views as genuinely scarce and decentralized.
The framing fits a longer pattern in how he engages with critics.
Earlier this week, he pushed back against billionaire Mark Cuban over Bitcoin performance claims after Cuban sold most of his holdings.
His warning carries weight partly because of who is making it. Back has been tipped as a leading candidate for Satoshi Nakamoto, Bitcoin's pseudonymous creator, a label that lends his market commentary outsized attention.
That rumor traces to an Apr. 8 New York Times investigation by Pulitzer winner John Carreyrou, who spent more than a year analyzing old cypherpunk mailing lists. The piece named Back as the strongest match yet for Satoshi. Back has denied it repeatedly, and much of the crypto community has questioned the linguistic evidence.
