On-Chain Data School (Part 2): The Evergreen Profitable Hodlers, What Was Their Cost Basis for Buying BTC?

On June 9, The Kobeissi Letter, citing Goldman Sachs data, reported that global investors are selling South Korean stocks at an unusually rapid pace. In the latest trading session, foreign investors sold about $801 million worth of Kospi constituent stocks again; total foreign outflows last week reached about $10 billion, and the market has been in net foreign selling on nearly every trading day over the past month. According to the data cited in the report, foreign investors have sold about $75 billion worth of South Korean stocks so far this year. Meanwhile, South Korean retail and institutional investors together recorded roughly $69 billion in net buying over the same period, suggesting that the market’s main buying support has come from domestic capital rather than returning overseas funds. The information currently disclosed still mainly comes from The Kobeissi Letter’s retelling and Goldman Sachs data summaries, while public details on the statistical period and the specific definition of “selling” remain relatively limited.

Fortune warned that Strategy’s Bitcoin treasury model faces growing financing risks as MSTR’s net asset premium narrows and preferred stock dividend pressure increases.

Sahara AI responded to SAHARA’s 60% price drop, saying no token contract or product security issues have been found and an internal investigation is underway.

In the fast-moving digital asset ecosystem, derivatives platforms face an extreme architectural test. High-leverage futures markets demand more than just standard security—they require absolute operational precision, zero-latency matching engines, and ironclad structural scalability, all while navigating intense market volatility.

As global platforms scale to meet these demands, the industry is shifting away from rigid, monolithic setups toward a more agile, "decoupled" infrastructure philosophy.

For elite global exchanges like WEEX (founded in 2018), this architectural choice becomes critical when scaling high-volume retail features like social copy trading. When thousands of users automatically mirror the real-time strategies of elite traders simultaneously, it triggers sudden, monumental spikes in concurrent transactional volume.

To prevent execution latency or settlement bottlenecks during these peak volatility events, a platform's primary engine must remain entirely dedicated to risk management, copy-trade synchronization, and order matching.

The Architectural Rule: New-generation platforms must separate front-end user execution engines from heavy backend infrastructural overhead to eliminate operational friction.

By separating these layers, platforms can maintain complete sovereignty over their trading environments and user experiences while strategically aligning with institutional-grade infrastructure ecosystems. This strategic framework allows modern exchanges to leverage advanced Digital Asset Custody infrastructure such as Cobo’s behind the scenes, ensuring that backend wallet management scales elastically alongside trading spikes.

In a derivatives arena where platforms offer up to 400× leverage on perpetual contracts, capital efficiency and market agility are core business metrics. To capture market momentum, an exchange needs the ability to rapidly expand its asset offerings, supporting everything from legacy crypto assets to sudden, trending altcoins across a massive library of trading pairs.

Adopting a flexible, scalable Wallet-as-a-Service (WaaS) solution such as Cobo’s could completely rewrite the development timeline for high-growth exchanges. Instead of spending months of engineering capital building out custom backend wallet architectures for every new blockchain network, platforms can deploy localized infrastructure in days.

This agility allows platforms to instantly scale their listings to over a thousand trading pairs without compromising security or delaying time-to-market. It mirrors the exact operational advantages seen during high-velocity market events, similar to how advanced wallet infrastructure empowers platforms during sudden asset surges; allowing exchanges to pass that speed and liquidity directly to their global user base.

The synergy between trusted infrastructure ecosystems and global trading platforms represents the natural evolution of a maturing crypto market. As WEEX continues to scale its global spot and derivatives offerings for over 6 million users, adopting robust backend paradigms proves that platforms no longer have to compromise between cutting-edge trading velocity and uncompromised structural security.
