The cryptocurrency market is witnessing an unprecedented wave of institutional investment, with Bitcoin ETFs leading the charge. According to blockchain analytics firm Lookonchain, the top ten U.S.-based Bitcoin exchange-traded funds have collectively seen net inflows of 29,321 BTC, equivalent to a staggering $2.78 billion, in just seven days. This surge in demand coincides with Bitcoin’s rally above $90,000, reinforcing the narrative that institutional players are increasingly viewing the digital asset as a reliable store of value and hedge against traditional financial instability.

The net inflows refer to the amount of Bitcoin entering these ETFs minus the outflows. What makes this influx even more significant is that it’s not isolated; it appears to be part of a sustained trend. Lookonchain’s data, published on the social media platform X, revealed that on April 25 alone, the ETFs brought in 5,037 BTC worth approximately $477.93 million. BlackRock’s iShares Bitcoin Trust was the standout contributor, absorbing 3,500 BTC valued at $332.07 million in a single day. The fund now holds a massive 586,164 BTC, which translates to roughly $55.62 billion in assets under management.

This surge in ETF activity underscores a growing appetite from traditional finance for digital assets, especially through regulated investment vehicles that provide exposure without the complexities of direct crypto custody. Data from crypto investment research platform SoSoValue confirms that as of April 25, investors have poured a total of $109.27 billion into U.S.-based Bitcoin ETFs. The influx is a clear sign that Bitcoin is evolving from a speculative asset into a foundational component of diversified institutional portfolios.

Ethereum, though trailing Bitcoin in institutional investment, is also experiencing a notable rise in ETF activity. Over the same week, nine Ethereum ETFs recorded total net inflows of 31,199 ETH, worth approximately $55.5 million. BlackRock once again took the lead, with its iShares Ethereum fund adding 22,704 ETH valued at $40.39 million. The fund now holds 1,184,959 ETH, equivalent to about $2.11 billion in assets. While the scale of Ethereum ETF investments is still relatively modest, the growing figures indicate that institutions are beginning to appreciate Ethereum’s potential as more than just a programmable blockchain—especially as conversations around Ethereum spot ETF approvals gain momentum.

So far, U.S.-based Ethereum ETFs have attracted $6.14 billion in total investments. While that figure is dwarfed by Bitcoin’s numbers, the increasing flows suggest Ethereum is solidifying its position as the second most favored digital asset in institutional finance. Its widespread use in DeFi, NFTs, and smart contracts further strengthens its long-term investment case.

While Bitcoin and Ethereum dominate institutional headlines, another player is making waves in the altcoin space—Sui (SUI), a relatively new layer-1 blockchain protocol. SUI has seen a massive 60 percent surge in price over the past week, reaching $3.53 at the time of writing. Unlike many altcoins that spike purely on speculation, SUI’s growth is being driven by tangible improvements in on-chain metrics and platform adoption.

Lookonchain reports that Sui’s total value locked (TVL) jumped 38 percent in the past week alone, reaching $1.645 billion. This increase indicates rising user activity and more assets being deployed in the Sui ecosystem. In addition, Sui’s decentralized exchange (DEX) volume soared to $599 million in a 24-hour span, representing a 177 percent increase from the previous week. Stablecoin growth on the network has also been dramatic, with the total value rising from $482 million to $879 million over the past two months—an 82 percent increase.

These figures show that Sui is not only gaining investor attention but also establishing itself as a serious contender among layer-1 protocols. The network’s rapid adoption and strong fundamentals suggest it could be one of the altcoins to watch during the current cycle.

In summary, Bitcoin and Ethereum continue to dominate the institutional landscape, with ETF inflows setting new records and reshaping traditional investment strategies. Meanwhile, rising stars like Sui show that innovation and user adoption are still key drivers of growth in the broader crypto market. Together, these developments point to a maturing digital asset space that is becoming increasingly integrated with the global financial system.
