I don't know, in my opinion when the market price is declining, mining and trading and bounty are risky because the market conditions can change suddenly, so the current bounty is not very profitable because there are too many ICO scams. But for gambling for me it's not on the list.
Yes, I agree, trading, mining and campaigns will also get lower income, so when the market crashes I usually gamble because we cannot always rely on only one hole, no matter what will happen but usually I sometimes get good luck and good profit at gambling when the market is crashing.
