It is actually very good job. I don't understand why he must leave the job.
Even if he can master trading, I am sure there is no guarantee to always get good profits in trading. If he want to full time doing bounties, it is also very risky.
I read a lot of suggestions for giving here so that we don't leave the real world's work to continue to have a sense. Because focusing on trading is also not always profitable, the Cryto market is very volatile and difficult to predict so we should still have a job in the real world. Participating in Airdrop also there is no guarantee that we will always get rewards, in my opinion Join Bounty Campaign Paid BTC is more certain we get Weekly Rewards.
The real problem is, if you follow investment, trading in crypto, do you need to leave your real-world job that you have been doing for a long time? Actually, all crypto jobs can still be done in between the jobs that have been done so far.
Besides having jumped in and focused on trading, which already has a guarantee with sufficient funds for trading, of course, it can be done, but it is not the main solution. If you can still do it in between jobs, but if you don't have time anymore and want to focus on trading, of course, that is an option.
Participating in airdrops, bounties have no guarantee of being able to produce results. Remember when the bounties in 2017-2018, the payments were very large. Now they are no longer there, so the situation is changing quickly.
