So, Vycid, have you exercised your puts yet or are you waiting still?
I've got some 3.2 puts expiring in a month that I'm unsure of whether I should exercise now or wait a bit longer.
If you exercise early you lose the optionality-value.
Better for you to hedge by buying some stock (which you can sell at expiry to the option writer).
Look up delta hedging.
Or sell them, but not sure btct allows that.
It's allowed. Better to reclaim the black-scholes implied value by selling.
