ARK Invest CEO Cathie Wood said on CNBC Thursday that bitcoin (BTC), the world’s largest cryptocurrency by market value, could reach $1,500,000 in price by 2030 in a bullish scenario, raising her estimate by 50% from a previous prediction of $1 million.

“We think the probability of the bull case has increased with this SEC approval. This is a green light,” said Wood on CNBC. On Wednesday, spot bitcoin ETFs were finally approved in the U.S. after a decade of trying. The Securities and Exchange Commission gave the green light Wednesday to key filings from the markets seeking to list the groundbreaking products.
