Today on Fintech Stacks, we break down three big stories shaping the public fintech markets. First, we look at BitMine (BMNR) and why the company is suddenly everywhere on retail investor feeds as it builds one of the largest Ethereum treasuries in the world. Then we check in on Circle (CRCL)—a stock that’s been volatile since its IPO but a company that continues to execute as stablecoins grow into real financial infrastructure. And finally, we dive into eToro, where trading volume surged 81% as investors shift away from crypto and back into traditional markets. Three companies, three signals about where fintech and trading culture are heading next.
