Ark Invest raises its bull market price prediction for Bitcoin in 2030 from $1.5 million to $2.4 million. This prediction is based on a new model that excludes long-term held or lost Bitcoins and only considers the circulating supply. The baseline scenario predicts $1.2 million, while the most pessimistic scenario predicts $500,000. The optimistic scenario assumes an annual growth rate of 72%, primarily driven by institutional investment. In contrast, the bear market and baseline predictions rely more on Bitcoin's role as 'digital gold' in emerging markets, helping users hedge against the risk of currency devaluation.
