You did the right thing, but less effective. Do not expect full from coins the bounty results, because not all coins have a market value. To get maximum results, try trading while participating in several projects, I think trading will be more effective to get the benefits that you expect.
Well, if you continue to rely on the bounty then there is no profit because it continues to spend a long time with uncertainty so that bounty income is not the best way at this time because bounty is not like it used to be.
If you have a little capital, better take advantage of short-term investments or daily trading.
if have a capital yes trading is the best then next would be investing ,followed by doing bounties as a side job . there are stil bounty left that pays small and small income is enough because its only a side job anyway but your main income can still go thru your trades and investment however its also better if you have a real job because real jobs outside cryptos are the best source of main income due to thier stability but with the corona crisis nowadays many jobs are stopped too so this should be the best way for cryptos trades/investment for a while
