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.
It is right to not rely on one hole only but you should not rely on gambling although sometime you get profit from it. Your luck wont come anytime you gamble unless you are the most luckiest player in this world. No one should rely on gambling no matter what is the condition of the crypto market. Relying on other thing such as your business your real job is more recommended. Just imagine that you lose all your asset while the market is crashing but few weeks later the market is back to normal and your asset's value increased significantly, that would be your biggest regret.
