Yes. Bitcoin is very volatile and can fluctuate in value quickly. Unlike other securities, the crypto market is active 24/7 and less regulated. In the past, Bitcoin's value has changed by $1000+ in a matter of hours.
As always, be careful when investing. Putting your life's savings in any single investment can be dangerous; cryptocurrency investments are no different. As with any high risk investment, we recommend only putting in what you're comfortable investing.
