Theoretically, any asset has the potential to go to zero, but for Bitcoin, the probability of going to zero in the short term is very low: it has been running for over a decade, has massive network hash power, and enjoys deep global liquidity and consensus. Its more realistic risk is extreme price volatility (short-term drops of 50% have occurred before).
Assets that are truly prone to going to zero are small-cap coins, scam tokens, and fraudulent projects with no real value. Beginners should prioritize mainstream coins and stay away from the temptation of "100x coins."
