If examined deeper, Bitcoin is speculative (in terms of value). The value is determined by the number of people or business units that accept Bitcoin. If more and more people use it, its value will continue to increase. Conversely, if it gets smaller, the implication is that the selling price will go down. Aside from being a crypto currency, Bitcoin is not familiar with transaction cancellations. The process is also public, there is no entity that can provide guarantees for negligence that causes loss or error in the delivery process. A hardware wallet (a special device for storing private keys) is also vulnerable to being attacked by a virus or damaged if not properly maintained, can cause coins to float.
