Patrick Shyu, the former Meta and Google engineer known online as Techlead, warns that quantum computing and decaying miner incentives are two undefused threats hanging over Bitcoin. Key TakeawaysPatrick Shyu says 95% of all bitcoin is already minted while the fee economy miners need “never showed up. ”Shyu sold his BTC in June 2026 after a 50% crash from $126,000, blaming excessive leverage for his losses. Bitcoin developers are weighing quantum fixes like BIP-361 as some researchers eye serious risk near 2030. A Warning Worth HeedingShyu, who served as a tech lead at Google and later as a staff software engineer at Meta before building a YouTube audience of more than a million subscribers, laid out his case ina recent video, zeroing in on the issues of quantum computing and the future of miner incentives, stating:I sold all myBitcoin, and I suffered absolutely massive financial lossesThe first bomb, in Shyu’s words, is the slow erosion of the network’s security budget. “Miners secure the network, and they have to get paid in two ways: either newly minted coins or your transaction fees,” he explained. The block subsidy is cut in half roughly every four years and currently stands at 3. 125BTC, with the next halving expected in 2028. The problem, he argues, is that new coins are running out and fees have not filled the gap. “95% of allBitcoinis already minted. The fee economy they would depend on never showed up,” Shyu noted, while further warning:As fees fade, miners switch off, security drops, the network weakens again… and a slow death spiral could set in. Bitcoinis over. Miner stress is already visible in the data as hashprice, a daily measure of mining revenue per unit of computing power, hovers around $29 per petahash per second this month, and miners absorbed an18% hashprice crashin late June asBitcoin’s mining difficulty jumped 7. 15%. The Quantum ClockThe second bomb is quantum computing because a sufficiently powerful quantum machine could, in theory, use Shor’s algorithm to deriveprivate keysfrom exposed public keys, putting olderbitcoinaddresses at risk. Timelines vary widely, as venture investor Nic Carter has pointed to a possible “Q-Day”around 2035, while other research published this year has shifted some planning horizonstoward 2030. Not everyone is in on the panic, with several academics concluding recently that attackingBitcoin’s mining process itself would require “the energy of a star,” and the industry has mounted a broad security race to quantum-proof the chain. Proposals include BIP-361, a three-phase soft fork that would eventuallyfreeze coinsthat skip migration to quantum-safe addresses, while Starkware’s chief product officer has published a scheme for quantum-safe transactionsbuilt from existing rules. Popular analyst Willy Woo too has argued the threat is already being met, pointing tosurging dev activityaround the issue. ‘Massive Financial Losses’Shyu’s own exit was as much aboutleverageas protocol design. “I used excessiveleverage. A small mistake led to dramatic consequences,” he admitted. Bitcoinfell from about $126,000 in October 2025 to the low $60,000s this summer, a drawdown of roughly 50% that triggered automatic liquidations of his leveraged position. He described the market as walking on “a thin layer of ice. ”Even after capitulating, the engineer insists he has not abandoned the asset class entirely, calling himself “still a long-termbullishinvestor. ” Critics have noted that Shyu has a history of dramatic reversals, and his warning landed during a week when the market moved the other way. Whether either bomb ever detonates depends on decisions still years out. The 2028 halving will cut the block subsidy to 1. 5625BTC, sharpening the fee debate, and developers have yet to coalesce around a single quantum-migration path.
