The consequences of the subsequent bitcoin halving could be significant. History may repeat itself (Price increase), or something else may happen.I have an optimistic view of the future of digital currencies after halving.since 1971, when the dollar was no longer backed by gold, the value of the dollar has fallen and the price of gold has risen against the dollar. Gold rose from $ 35 per ounce in 1971 to $ 1,500.If the lack of gold makes it superior, Bitcoin is far superior to gold.Gold shortages and high demand from global institutions, individuals and central banks are the main reasons why the value of the gold market has reached more than $ 8 trillion. Now imagine that there was a basic metal that was as small as gold and had another special feature; [Bitcoin] could be transmitted through communication channels.
