Of course, signature campaign paid in BTC is the best one to join nowadays. The payment is clear, we get the payment every week. It is very different if we join the signature campaign paid in new altcoins, the payment is clear. Sometimes the new altcoins have no values when we receive it. It is also not so different when we join the bounties paid in new altcoins. Regarding trading, I think it deserves to do. But trading requires good knowledge, skills, and experiences.
Some say that to be successful, one must dare to make decisions... there is no success without risk, so if you want to advance and be more successful in the cryptocurrency world, just following bounties will only make you live, but if you want to live happily, then invest... the rational choice at this time is if you already have an income from a job in an office near your home, then the payment from the bounty or campaign can be allocated for investment needs... it doesn't matter how small the amount is, as long as it is routine and consistent, at least in old age you won't feel confused anymore...
Between bounty and investment, I can recommend both of them to copy related.. because investment opportunities are still big until now, and it can really be expected to be a savior in old age.
