Back in 2009, when the first Bitcoin was mined, its value was 0$. Ever since then, the crypto has gained immense value and has never lost its entire value despite its volatile nature. In fact, every time crypto halving occurs, Bitcoin sees a massive spike in value due to shortened supply and increased demand. So, at least up till now, nobody has lost all of their money in Bitcoin. Analysts suggest that Bitcoin and other cryptos should be held onto for longer time periods because they're volatile but have great potential in the long run.
