Bitcoin’s Payment Future Viewed as ‘Optional Upside’ by BlackRock
BlackRock’s digital assets chief, Robbie Mitchnick, says that the idea of Bitcoin one day becoming a mainstream payment rail is not what’s motivating most institutional investors today.
In a recent podcast appearance, he explained that clients aren’t evaluating Bitcoin through the lens of a global payment network; instead, they see that possibility as a distant “optional upside,” not a core part of the investment thesis.
Mitchnick noted that widespread payment usage isn’t impossible, but current interest centers almost entirely on Bitcoin’s role as a store of value – the “digital gold” narrative. Shifting that dynamic would require major progress on scaling tools such as Lightning and various layer-2 approaches, many of which still face long-term viability questions. Galaxy Research even suggested last year that several Bitcoin rollup designs may struggle to remain sustainable despite their popularity.
While Bitcoin’s payment future remains uncertain, Mitchnick pointed out that stablecoins have already demonstrated strong real-world utility. He described them as one of the most successful crypto products to date, noting their efficiency in moving value and their potential to expand far beyond crypto trading and DeFi.
He expects significant growth in areas like remittances, cross-border corporate transfers, and settlement processes. Compared to those sectors, he said Bitcoin may realistically compete only in retail remittances for now, although he isn’t ruling out broader use cases in the long run.
The rapid rise of stablecoins is also influencing broader market forecasts. ARK Invest’s Cathie Wood recently attributed her more conservative 2030 Bitcoin outlook to the pace at which stablecoins are scaling, arguing that they’ve absorbed roles she once expected Bitcoin to dominate. She previously projected a $1.5 million target but now believes trimming that estimate by around $300,000 may be reasonable.
Other industry voices see stablecoins becoming even more dominant. Tether co-founder Reeve Collins told Cointelegraph earlier this year that he expects nearly all forms of money to transition into stablecoins by the end of the decade as more financial activity moves onchain.
