## @hTprCcgjJ8mHs7Y (内田容平) · 09-20 12:15 · ♥74 ↻3 💬3 そして、ここからがPiDEXに注目したい理由。
もしPiDEXが今後、本格的な流動性基盤として機能するようになれば、Piは単なる「決済に使える暗号資産」から、 人・DApps・資産・流動性をつなぐ経済圏へ進化する可能性がある。
DEXは単にトークンを交換する場所ではない。
流動性が集まり、DAppsが接続され、DeFiやRWAなどの新しいサービスが生まれれば、そこには新しい経済活動が生まれる。
Solana、Ethereum、BNB Chainなども、エコシステムが成長する中でDEXやDeFiが重要な役割を担ってきた。
だからこそPiDEXにも注目したい。
「Piの価格はいくらになるのか？」
だけではなく、
「Piを使って、どれだけ大きな経済圏を作れるのか？」
ここを見るべきなのかもしれない。
もちろん、PiDEXがどこまで発展するかは現時点では決まっていない。
でも、もし Pi Network × PiDEX × DApps × DeFi × RWA
という流れが本格的につながったら――
Piは「一つの暗号資産」ではなく、 巨大なP2P経済圏を支えるインフラになっていく可能性がある。
だから面白い。🥧🚀
PiDEXのこれからに注目したい。

## @SolanaLegend (Solana Legend 🎒💧) · 09-20 12:00 · ♥57 ↻6 💬8 Really happy to see solana:BPxxfRCXkUVhig4HS1Lh7kZqV6SPJhzfEk4x6fVBjPCy getting the respect it deserves. Worth noting it isn't listed basically on *any exchanges* apart from @solana and @Backpack itself yet. Show me another top exchange, tokenization platform, wallet, and DeFi ecosystem that has these tokenomics... I'll wait. https://x.com/SolanaLegend/status/2101642601585607125
