I will choose campaign. No money will be required to campaign and there is no risk. I earn good money by bounty. On the other hand, trading and gambling both are risky and capital required.
Talking nowadays that taking part in the campaigns you risk nothing is not true. I agree, you do not risk your own money, but you risk something else that can also be valuable - your own time. Some time ago I spent hundreds of hours translating the topics ANN and whitepapers, taking part in bounyt campaigns, unfortunately from a dozen projects, each of which offered thousands of dollars today, only 3 have been on the market and my earnings for these hundreds are only a few hundred dollars. If I devoted these hours to a different job, I would certainly go out better ...
You may not need to spend so much time. You can do this on break or when you dont have to work something. But spending 2-3 hours a day for campaign it not that hard i believe. Most time campaign and bounty manager are spending on this they need to check everything. Dont know how much they are receiving but ho matter how much they get they should receive double every time.
