OKX Experts Discuss Bitcoin’s Transition to a Fee-Driven Security Model Post-2140

As Bitcoin approaches its maximum supply of 21 million coins by 2140, the cryptocurrency community is preparing for a significant shift in its economic model. Experts from OKX Singapore, JuCoin, and XBO emphasize the importance of transitioning to a fee-driven security model to sustain the network once block subsidies cease. Gracie Lin, CEO of OKX Singapore, underscores the critical nature of this evolution, highlighting the need for transaction fees to adequately compensate miners and maintain network integrity. This article delves into the insights shared by these industry leaders and explores the long-term sustainability of Bitcoin's blockchain.

Bitcoin’s Endgame: Network Sustainability Post-2140 Mining Completion

Bitcoin’s fixed supply of 21 million coins will be fully mined by 2140, eliminating block subsidies that currently incentivize miners. Experts from OKX Singapore, JuCoin, and XBO suggest the timeline allows adequate preparation for a fee-driven security model. Transaction fees must compensate for lost subsidies to maintain network integrity.

Gracie Lin, CEO of OKX Singapore, highlights the critical shift: "Bitcoin’s security will depend fully on transaction fees." The central challenge lies in scaling demand for block space to justify premium fees. Institutional adoption and retail activity are projected to fill this gap—if growth trajectories hold.

Concerns linger over potential centralization risks and the network’s adaptability. The halving mechanism, which periodically reduces mining rewards, has historically reinforced Bitcoin’s scarcity. Yet its long-term viability now hinges on organic fee market maturation—a test of economic design unprecedented in monetary history.

$PUMP Plunges 8% Amid Meme Coin Sell-Off, Buybacks and V2 Upgrade in Focus

Pump.fun's native token $PUMP tumbled 8% to $0.003138 as meme coins faced broad selling pressure on August 18. The decline follows a transfer of 2.5 billion $PUMP tokens (worth $9 million) to OKX exchange, signaling potential liquidation pressure from large holders.

The project is countering bearish sentiment with an aggressive $8 million buyback program and upcoming V2 upgrade. Market dominance metrics suggest $PUMP could lead the next meme coin rally if support levels hold. Analysts note the token's volatility reflects both speculative trading and strategic accumulation by smart money during dips.
