Ark Invest CEO Cathie Wood suggests that Bitcoin's traditional four-year price cycle may be losing its impact as institutional investors increasingly buy and hold the cryptocurrency. This shift is attributed to the growing influence of ETFs and firm holdings, which are locking up coins that were previously traded by retail investors. While on-chain analysis indicates that Bitcoin's patterns still resemble past cycles, Wood notes that macroeconomic factors, such as interest rates, are now playing a more significant role in influencing Bitcoin's price movements. Ark Invest has recently acquired shares in Coinbase, Circle, and its own Bitcoin ETF, reflecting its strategic positioning in the evolving crypto market.
