Pi Network is a cryptocurrency project that aims to make cryptocurrency mining accessible and easy for everyone using smartphones. It was developed by a team of Stanford University graduates and launched on March 14, 2019. The platform allows users to mine Pi without the need for advanced hardware or consuming large amounts of energy, making it environmentally friendly and more accessible.

Network development stages:

1. Enclosed Mainnet: At this stage, Pi transactions were limited to a closed ecosystem, where users could only use their coins within approved applications and platform services.

2. Open Mainnet: As the project progresses, Pi Network is preparing to launch its open network, which will allow users to freely transact Pi and trade it on open markets. This launch is expected to take place in 2025, after completing identity verification (KYC) and linking accounts to digital wallets.

Challenges and concerns:

Despite Pi Network’s rapid user base growth, surpassing 70 million users by January 2025, there are some critics who suggest that the referral- and marketing-based growth model may raise concerns about a pyramid-like structure. However, proponents of the project maintain that this approach helps build a large community before the currency becomes tradable in foreign markets.

Future expectations:

As the open network's launch approaches, analysts expect Pi to be worth between $0.35 and $1.6 by 2025, with the potential for even greater increases if the project succeeds and expands.

Conclusion:

Pi Network offers an innovative model in the world of cryptocurrencies by facilitating the process of mining via mobile phones. However, those interested in the project should carefully monitor its developments and potential challenges before deciding to participate or invest.
