it is a wonderful event to test the knowledge to predict the future result.

higher return with lower risk?

It is getting better day by day.

not bad, but can be better.

just no real estates & cryptocurrency.

Just buy and hold.  trade when the price is right.

passive index.  good for me as I don't have much time to time the stock market.

not seeing any good use of this...yet.

it is a good way to gain knowledge / experience without the fear of losing money. with enough confidence in trading and stock picking, going into the real market will be more profitable and less worry.  so someone can sleep better at night.
