I remembered watching a video about bitcoins and the simple information that a beginner can understand. It says that bitcoin only has the maximum of 21 million bitcoins and 17 or 18 million has been mined.
What would happen if the very last block were mined? Will the value of bitcoin finally be stabilized?
Bitcoin and cryptocurrency or even currency doesn't have stability. If it is stable it will be easy for everybody to choose there will be much problem. The price of the currency depends on the behaviour of the coin. Buying or selling is a decision to make you just have to have so much background and knowledge upon what you do with your finance.
