In a “21 and 21” rapid-fire interview with Haley Berkoe at San Francisco’s Presidio Bitcoin workspace, Jack Dorsey—CEO of Block and former Twitter chief—cautioned that BTC’s growing popularity among major financial institutions could threaten the open ethos that gave rise to the world’s largest cryptocurrency.

“It probably harms it a bit,” Dorsey said when asked about institutional investment in Bitcoin. Yet he acknowledged that large-scale involvement is practically inevitable, adding, “I think it’s obvious that we’ll see more of it, and I hope that more people take on the principles of what made Bitcoin successful in the first place.”
