In the morning I read the news where one of the leading multinational finance company stats that the Bitcoin & Other Cryptocurrency will be zero. So is it possible? If possible then which instructions should be followed getting out of debt?
It is possible but highly unlikely due to its existence already bringing positive impact to the society.
Though it may be relative, some countries are exhausting its nature in order to provide the society an alternative means of earning income in a short-amount of time as compared to other investment mechanisms. The reason on why it is possible mainly focuses on the government's capacity as the controlling body of the state. If the government has declared the prohibition of bitcoin on their country, expect bitcoin prices to significantly decrease (i.e. China has banned malicious ICO companies, SK has imposed strict rules and regulations, etc.).
The question is, what if all influential countries that contain large market and trading industries have announced that they will prohibit bitcoin among its transactions? Expect prices to decrease and decrease until it becomes obsolete to the system.
