Can a Small Miner Attempt a Double-Spend Attack?

A small miner can attempt a double-spend attack, but the probability of success is extremely low, approaching zero. A successful double-spend requires the attacker to secretly mine a longer chain than the honest network's chain, which is statistically improbable without a significant portion of the total hashrate.

Any attempt by a small miner would likely result in their secret block being orphaned immediately.
