Hi there,
I think that if it's not regular options with regular expiry ( Nov, Dec and so on) you don't trade something you don't know.
I know many people like to trade on weekly options since they can make more money fast which at the end of the day lose more money fast...and also mini options it's a new tool to trade on big tickets 10 contracts instead of 100 .
it was very popular before $AAPL split and went back to $90 so people could buy options on that stock. again, it's another way to lose money on a smaller scale :)
I will stick to selling options since this is what I know best and for long term this is what will make money to everyone and not buying options not weekly and not mini and not any other stuff they will invent for people that buy options will lose money on.
But that's just me...:)
