PI coin, also known as Pi Network, is a virtual Monnaie numérique developed by a team of PhDs from Stanford University. The project aims to make Bloc chain Mining accessible to everyone through a mobile app, lowering the threshold of traditional Cryptocurrency Mining. The total supply of PI coins is 21 billion, with a relatively large Circulating Supply at present. Although PI coin has not yet been fully listed on mainstream plateforme d'échange, its unique mining method and large user base have attracted a lot of attention. However, PI coin also faces multiple challenges such as listing on plateforme d'échange, ecosystem construction, regulatory policies, etc., making its future development full of uncertainties. Investors should handle the investment risks of PI coin cautiously.
