The buying and selling of bitcoin can be hard. That is why people often times been hodling it to ensure long term survival. The price will go up they claim, since the innovative product is still young. Before swinging back and forth like some animal from Madagascar.
It is the safest bet. But the key concept is that there is a buying and a selling of a price of an asset. A digital one at that. Like gold it is supplemented by supply and demand. having a limited supply of 21 million. and a running supply from that time of somewhere in 16 million or lesser. Now, in 2025, its above 19 million or more.
You buy based from the standard price per bitcoin. You sell when the price for you is higher than the set up price you previously claimed it. Then buy it, when you think the margin or makeup price is low to that of what you deemed it to be low. In that sense, it is like a normal produce or commodity in trade that you make sure to buy low and sell high. Which gave bitcoin its market opportunity and appearance to ensure that it always has a fair price, and pricing in the market.
In using it, you need to have its private keys so that you will receive it at a certain wallet address. Which often times, you can choose which bitcoin address you can use. In this time, giving you randomly generated new ones for you to take. Previously, it is stored as a form of cold storage in usb sticks. Now, we have hardware wallets for it, and even online ones that require you to even have a seed.
In sending, you need to put the recipient's bitcoin wallet address to send some. With a fee for transaction called a transaction fee in a standard wallet. To pay miners the share of their job in keeping the system safe and as well operating the transaction. In this aspect, no bank is needed. Then, in receiving the bitcoin, you need to wait for the transaction to be completed. Each block is mined every 10 minutes, giving the miners time to earn block rewards upon completing the ledger. In this sense, they earn with both the rewards and the transaction fees they operated at.
