Gambling is the most risky one to bet our earnings. Some people might gamble for entertainment but people who are addictive to gambling will not bother how much they lose the money. So we have to find other sources of income in order to work for bounties and trading.
Gambling is risky but its also verry rewarding . you can double your cryptos/cash in an instant and you can win big if ever you get lucky to hit the jackpots but this shouldnt be prioritize as our main source of income because there are other less riskier activities that we can do out there to be able to earn . like what you guys said , i do also recomend bounties or airdrops since both are free and you can also earn good profit compare to faucets or even mining..
