Bitcoin News Today: Inflation Fuels Bitstack's $15M Rise as Bitcoin Savings Surge

Paris-based Bitcoin savings app Bitstack has secured a $15 million Series A funding round led by 13books Capital, marking a significant milestone for the startup as it expands its European footprint and introduces new financial products. The investment, which includes participation from returning backers such as AG2R LA MONDIALE, Plug and Play Ventures, and Y Combinator, will accelerate the company's growth across a dozen European markets and fund the launch of its innovative VISA debit card with a Bitcoin rewards program. The round underscores growing institutional confidence in crypto savings tools, particularly in inflationary environments where Bitcoin is increasingly seen as a hedge against currency devaluation according to market analysis.

Bitstack's core offering-automating savings by rounding up everyday purchases and converting spare change into Bitcoin via dollar-cost averaging-has resonated with nearly 300,000 active users in France and beyond. The company's revenue has grown tenfold in two years, with users collectively saving over €300 million in Bitcoin since its 2021 launch. Its product suite now includes a euro account with a French IBAN, enabling seamless salary conversions into Bitcoin, and a localized VISA debit card featuring a "Stackback" rewards system offering up to 1% cashback on purchases. The app's MiCA license, secured in June 2025, further strengthens its regulatory compliance and competitive edge in a fragmented European market .

The funding arrives amid broader macroeconomic trends. Eurozone inflation has risen 23.4% since 2020, driving nearly 4 million French adults to adopt Bitcoin as a store of value. Bitstack's co-founder and CEO, Alexandre Roubaud, emphasized the "exceptional growth" of the platform, attributing it to economic uncertainty and the euro's eroding purchasing power. The startup plans to roll out its VISA debit card in a beta phase starting January 13, 2026, with 5,000 waitlisted users initially.

Competitors like Revolut, Bitpanda, and MoonPay face challenges matching Bitstack's disciplined focus on Bitcoin savings and its rewards-driven engagement model. Michael McFadgen of 13books Capital highlighted the startup's potential to dominate the sector, noting its "product suite and regulatory readiness" position it as a leader in Europe's crypto savings market. The investment also aligns with broader trends in crypto adoption, as spot Bitcoin ETFs recently reversed a four-week outflow streak, signaling renewed institutional interest .
