Why Bitcoin was created? What are its advantages and disadvantages? How to earn Bitcoin? How much money can be made by selling Bitcoin? Who bought Bitcoin? If we say Bitcoin in simple language then Bitcoin is digital money which no one can touch but it has a price. In many countries it is possible to pay with Bitcoin but still buy something with Bitcoin in Bangladesh. It is not possible. Bitcoin has an advantage and no one has control over it. No one can reduce the price of Bitcoin if they want to. The price of Bitcoin depends on how much or how little Bitcoin is in the market. At present everyone is unemployed at home during Corona. There are websites that pay you some bitcoin in exchange for viewing advertisements or ads (40 minutes of work per day per website) which is much less but if you work on 4, 5 such websites then you can earn at least 1 thousand rupees per month. Now it is a matter of who buys bitcoin. There are many people who trade with bitcoin which requires a lot of bitcoin to do so those who earn bitcoin do not have to worry about selling bitcoin. Bitcoin should be sold after a good check before selling Bitcoin.
