Bounties are good but i think it gives us rewards after a long period on the other hand trading gives us instantly but i think do trading with enough knowledge about market.
So from that people prefer to do work in the bounty even for a long period of time. At least they are doing the best for now. I think trade is certainly profitable but basically the risks in trading are very high. So if people aren't ready to trade, of course they aren't recommended there.
Indeed, bounties require a long period to make them but they are also not risky in case of money investing. Therefore, bounties are really good choice for those one who are not ready to take a risk.
Surely it is really good because we get the chance to buy some coins at free of cost and we can get money as well, for bounty you will have to use your skills and knowledge only but the reward will surely be higher, trading also has allot of opportunities for us but it needs fine skill and information about trading, so those who can trade well are now rich people of my society as trading has plenty of profit for traders.
