How much money did you turn into 500k? Predicting the consequences of a once in a lifetime black swan event is surely very lucky. But fortune favours the brave as they. You will never win a lottery if you dont buy the goddamn ticket!
Initially I put about €65k into put options. The crash came so fast that it turned into a lot more very quickly. If your bet turns green instantly, you don’t see the risk. I couldn’t do the same thing again. I was very naive, but it helped me to hold with conviction.
Glad you seemed to have learned that you were playing with fire, since that could have easily left you with 65k in the red.
