Bitcoin’s Long-Term Survival Questioned by Ethereum Researcher

Ethereum Foundation researcher Justin Drake has issued a stark warning about Bitcoin’s long-term viability, questioning the sustainability of its security model based on proof-of-work (PoW).

In a detailed analysis shared online, Drake argued that Bitcoin’s diminishing block rewards and historically low transaction fees could jeopardize the network’s safety. With daily transaction fees reportedly below 10 BTC—representing just 1% of miners’ total revenue—he suggested the network is heading toward a severe security deficit.

Drake claimed that Bitcoin’s capped 21 million supply, combined with its reliance on fees, could render the system economically fragile over time. He warned that if block rewards continue shrinking while fees remain stagnant, even a fraction of today’s mining capacity could potentially launch a 51% attack.

According to Drake, Bitcoin’s sustainability depends on either adopting a new issuance model—such as “tail issuance,” which adds ongoing inflation—or replacing PoW with proof-of-stake (PoS). However, he acknowledged that both solutions face strong cultural resistance within the Bitcoin community.

He also dismissed layer-2 scaling solutions and newer projects like Ordinals and BitVM as temporary fixes that fail to address the underlying issue of declining miner incentives.

Drake concluded with a sharp message: unless Bitcoin’s monetary and consensus models are restructured, the network could face existential risks as its security budget erodes.
