We know that four way to cryptocurrency income such as Invest ico, mining, trading and Airdrop-bounty. If you wish, you can do any of that.
If you want to mining or invest in ico and need a lot of money, it has cost-effective risks and have also profits. And if you want to do trading then you can start trading only if you have some money. Here's a little less risk and have also profit.
If you do not want to take a risk then you can start the bounty. There is no risk here only you will have to work on time and you will get your payment at the end of the job. As a payment, you can get cryptocurrency and convert them into meaning by selling them. So, I think Bounty and airdrop is very good for earning risk-free cryptocurrency profit.
Not all bounty now are giving payment to their bounty participants. Most of the ico bounty campaign this 2018 was turned into scam and some are extended in a long period of time. Meaning, the effort of the participants was all turned into useless effort. Although, some of your statement was indeed true. But most traders nowadays are bullish.
