Quant-driven trading firm TDX Strategies has suggested a "bullish risk reversal" strategy that involves selling a put option (insurance against a downtrend) and using the premium earned to buy bullish call options. This strategy effectively funds bullish bets while remaining exposed to a bitcoin rally. This move reflects a shift towards more sophisticated, options-driven positioning as traders seek to increase risk. The strategy requires close monitoring and may not be suitable for new investors or those with limited capital or a weak grasp of options dynamics.
