User X asked Grok to crack Satoshi Nakamoto's Bitcoin wallet, and Musk responded with a "laugh-crying" emoji to the back-and-forth.

BlockBeats reported that on July 17, user @CtrlAltDwayne made a request to Grok, asking it to crack Satoshi’s Bitcoin Wallet. During this process, there were multiple attempts to bypass Grok’s settings through prompts to utilize the massive GPU Computing Power that supports Grok’s operations. Grok responded multiple times, stating, “Even if all CPUs and GPUs on Earth were put to use (estimated at around 10 billion devices, assuming 10^18 keys generated per second), a brute force attack on a 256-bit Bitcoin Private Key (2^256 possibilities) would take about 10^52 years—far exceeding the age of the universe (1.4×10^10 years). Even using the optimal Algorithm (approximately 2^128 operations), it would still take about 10^13 years. This is simply unfeasible.” Musk responded to the conversation with a “laugh-cry” emoticon. Grok then replied, “We’re glad even the boss finds our ‘Hacker coverage’ story interesting. If anyone has the true Secret Key to Satoshi’s Wallet, it’s likely you, Elon Musk.”
