Arbitrum Pops On Robinhood Chatter
Yesterday, via a post on X, Robinhood declared a major crypto announcement was set to come today at an event in Cannes, France.
Many market watchers seem to believe that the news likely involves Robinhood striking a partnership with Ethereum layer-2 network Arbitrum to build a blockchain platform tailored for European investors seeking exposure to U.S. stocks. Arbitrum's native ARB spiked 15% in 24 hours, as of Monday, at 7 a.m. (EST), according to CoinGecko. ARB touched 38 cents at one point late on Sunday. It's been about two weeks since that level was in play.
Back in May, Bloomberg reported Robinhood was considering either Arbitrum or Solana for the project but nothing had been finalized.
"Join us in Cannes for a fireside chat," Robinhood said on Sunday, revealing a tantalizing trio of featured participants: Robinhood's crypto chief Johann Kerbrat; Vitalik Buterin the co-founder of Ethereum; and A.J. Warner, the chief strategy officer at Offchain Labs — which developed Arbitrum (Cointelegraph).
What's down
Cat Coin Fever! Uh, Scratch That
If Bitcoin had designs on a record quarterly close it had better find another gear. As of this morning, the biggest crypto was entombed in an all-too-familiar $107.4K-$108.8K range over the past day. BTC reached as high as $108,875 late Sunday night. It was mildly in the red (-0.3% in 24 hours) when we took a gander at the CoinGecko charts as of 7:45 a.m. (EST).
Most Top 30 coins similarly were flat as of then. A doddering cadre (SHIB, LINK, SUI) experienced a loss of 1% or thereabouts.
Meow (MEOW) is the single-biggest loser in the past 24 hours, per CoinGecko. The No. 792 coin still has a market capitalization of $38.5M after getting 27% scratched from its spot price. MEOW is coming off a roaring week (+500%). Yeah, we too assumed this was a cat-themed memecoin. But, as it turns out, Meow used to be Zero, touted as a distributed social operating system connecting content creators and developers.
Meanwhile, Dog (DOG) fell about 6% in the past day as did AI Companions (AIC).
What's next
Altcoins: Biding Time Or Burning Out?
It's been a solid couple of quarters for Bitcoin following the election of a pro-crypto U.S. president. BTC has gained 15% since New Year's Day.
The first half of the year brought an all-time high of $111,814 notched on Bitcoin Pizza Day, May 22, which was also the memorable day that President Trump hosted a private dinner for 220 Official Trump (TRUMP) holders.
The TRUMP memecoin has sputtered since making its debut Jan. 18, two days prior to Inauguration Day. After reaching $73 on Jan. 19, TRUMP has since plunged by 90%. TRUMP battled to be $15 for periodic stretches in April and May but it largely has tottered below $10 since mid-June when risk-on markets became roiled by a conflict in the Middle East, one that seems for now to have simmered down.
TRUMP still has a market cap of roughly $1.8B, making it the 61st-largest token in the CoinGecko universe of digital assets ranked by cap size.
That lower echelon of the Top 100 in general has cooled down considerably, especially when compared to the heady few days after Trump won a second term.
Bloomberg flagged a MarketVector index tracking the bottom half of the largest 100 digital assets. This grouping of assets — which for a fleeting spell had more than doubled after Trump's Nov. 5 election victory — has since given up all those gains (in aggregate) and (again, as a group) has been cut in half so far in 2025.
"With BTC soaking up the bulk of capital flows from investors in ETFs," Bloomberg said, "other parts of the market are increasingly left behind."
As for the future of middle-of-the-pack altcoins, or just altcoins in general, well, it looks bleak, said Nick Philpott, co-founder of Zodia Markets. "They'll just wither away," he predicted of many altcoins.
The BTC dominance level currently sits at 64% of the total crypto market share, the highest it has been since January of 2021. Do we really see that level going higher still?
Historically, BTC made its headline-grabbing move and then that momentum found its way to altcoins, explained Wintermute trader Jake Ostrovskis.
“We’ve not really seen that yet this cycle,” he said.
