Bitcoin's 20% post-ETF slide threatens exchange-traded FOMO. The recent 20% drop in Bitcoin from its recent high is worth scrutiny, given the hype accompanied the run-up to the launch of exchange-traded funds that invest directly in the original cryptocurrency. Reasons for the drop include 'buy the rumor, sell the news' when it comes to ETFs, higher interest rates, a stronger dollar, and outflows from the bankrupt FTX exchange. The key question now is whether the tumble itself will prove to be its own catalyst to frost over the green candles that seemed to mark the end of the latest crypto winter. The launch of the ETFs was expected to send Bitcoin to a new record high, but the breathless predictions now seem suspect. The upcoming halving, when the supply of new tokens gets cut in half, could be the ultimate near-term test of the potential demand for the new ETFs.
