Why this strategy and not just DCA?

$SPDR S&P 500 ETF (SPY.US)$ There is a legitimate and serious concern that SPY may go to 300-350$ in the coming months if it hits bear markets. More of not "if" but rather "when" it hits. I do not want to run the risk of losing my investments by such a large percentage, and hence hedging seems to be the best option at the moment. Of course keep cash on the side and invest as it allows. And, given the conditions, buying these spreads and selling at 50-80% profits seems to be the best strategy.

Positions: SPY 400-390 Put debit spread expiring June 21st (why? this is after CPI data and FED meeting, although I feel FED meeting may not cause much issue, as Powell announces everything upfront). Bought at $3.21 per contract, already up 60% as of right now).

There is a good chance of bull run to 420$, could add more if that happens. I wish it happens really and these debit spreads goes to ZERO..... I will be more happy to see my investments go up and not worry about hedging.
