Tech billionaire Peter Thiel has voiced doubts about Bitcoin’s capacity for significant price growth while also expressing regret for not purchasing more of the cryptocurrency. Thiel, who co-founded payments giant PayPal and the Founders Fund, expressed skepticism about King Crypto’s price potential during a recent CNBC interview, saying, “I’m not sure it’s going to go up that dramatically from here. We got the ETF edition, and I don’t know who else buys it.”
