Adam Back: Markets Repricing Memecoins; ‘Buy Bitcoin, Hodl’

Blockstream CEO Adam Back posted on X on May 23 and 24, 2026, saying efficient markets are repricing memecoins, smart-contract tokens and other ‘air tokens’ toward zero and urging investors to buy and hold Bitcoin.

Back argued most alternative tokens lack three features he regards as necessary to sustain value: they generate no cash flows for holders, they attract little meaningful blockspace demand and they do not have durable competitive advantages. He wrote he expected the efficient market hypothesis to affect alternative tokens years ago and that he was surprised it took this long for the correction to begin. He summarized his guidance as ‘buy bitcoin, hodl, repeat.’

The comments came as Bitcoin and the wider crypto market reacted to political developments. Bitcoin fell to a four-week low after a delayed vote on the Clarity Act, then rebounded after reports of a ceasefire between the United States and Iran produced a broader market rally. Back observed that Bitcoin captured most of the rally while most altcoins failed to sustain gains from the same macro catalyst.

Back is the inventor of Hashcash and a long-standing Bitcoin proponent. Earlier in the week he pushed back on investor Mark Cuban’s performance claims after Cuban disclosed he had sold most of his Bitcoin holdings. Back used data-based arguments in those exchanges and in his posts about scarcity and decentralization as the basis for Bitcoin’s value.

Back has made similar forecasts in previous market cycles and said he first made the call about a decade ago. Some market participants say it is unclear whether the recent decline in altcoin prices will continue toward near-zero values or whether some projects will find a stable floor above zero. Back’s publicly stated strategy remains to accumulate and hold Bitcoin.
