Bitcoin's value can be quite volatile and can fluctuate greatly in a short period of time. It's important to note that the value of bitcoin is determined by supply and demand on the open market, and can be influenced by a variety of factors such as regulatory changes, mainstream adoption, and investor sentiment. Additionally, the market for bitcoin is still relatively new and not well understood by many, which can lead to fluctuations in value. It's important to do your own research and understand the risks associated with investing in bitcoin before making any decisions.

Owning an NFT, such as The Greedy Machines series, means that you have a unique, digital asset stored on the blockchain. This asset represents ownership and proof of authenticity of that particular NFT, and it can potentially have value based on factors such as scarcity, demand, and utility. In the case of The Greedy Machines, these NFTs are backed by real computing power, which can allow the holder to earn BTC through mining. Additionally, the power of each NFT can grow as new collections are issued, and holders can participate in game functions through their personal account on the "Mining Farm" page.
