Adam Back Warns Altcoins Headed to Zero as Bitcoin Holds Near $76,852

On May 25, 2026, Blockstream CEO Adam Back renewed his decade-old prediction that many altcoins and memecoins lack long-term value and could fall to zero under efficient-market pricing. Bitcoin currently trades near $76,852, up 2.59% over 24 hours, after dropping roughly 40% from its all-time high above $126,198 to a low of $74,197. Market conditions show Bitcoin dominance near 59%, a total crypto market cap of $2.7 trillion, nearly 40% of altcoins near all-time lows, and memecoins holding $34 billion in value led by Dogecoin and Shiba Inu. The remarks reinforce bearish narratives for lower-quality tokens while highlighting continued capital concentration in Bitcoin.
