Bitcoin has been growing more and more popular over the years. The image above shows how daily bitcoin transactions are indeed growing over the years. This effect is based on the cause, witch, in this case is people becoming more digital over the days. You see, bitcoin prices can be, for example, 752 USD one day and 719 USD the other. These prices are determined by how much the [bitcoin] sellers and buyers are willing to pay. A special program will average up the prices the [bitcoin] sellers and buyers are willing to pay and make it “internet-wide”. There is also another thing called the spread, [bitcoin] sellers and buyers try to make the spread as low as possible is because the bitcoin demand will be low if the spread is very high. The spread shows the difference (subtraction) between the buyers and sellers with the closest price they want to sell or buy (sorry, hard to explain, visit https://www.gdax.com/trade/BTC-USD for clarification). If you have a BitPay wallet or another type of bitcoin wallet, don’t be surprised that one day you have 15.87 USD one day and 15.37 USD the other, this is because the bitcoin price is changing.TIP: Don’t bother to check the bitcoin price daily, that way you know how much to send to your contacts or whoever you want to send bitcoins to.
