Bounty actually doesn't help much these days. Investors do not come to this forum so the only purpose for conducting bounty could be user awareness. Projects are using different methods to do their marketing and most of them are effective though they are most costly than others. Running bounty is not a great option if you want to raise funds for your project.

Don't have high hopes for the bounty, because the bounty now compared to the past is very much different.
But actually there are still many paid bounties and can make money, but the amount is indeed small.

Most of the hunters are shifted to other source of income. Those who are still here do not have any alternative i think and most of them get very little paid from a project. But as you have said there are still some project that is giving real value to the hunters and that gives hope to hunters to continue their work.

Trading gives holder a chance to increase his portfolio without putting any extra money into it. If you sell your BTC at 60k and buy back at 30k then you have 2X BTC than those long term holder who do not sell their BTC at any time. It is all about your investment strategy and if you can use it well then you could be the most successful trader.

There are some scam detector group that verify project authenticity. You can follow those group in telegram and twitter to stay away from scam project.

We can use crypto legally if govt regulate crypto. Many big companies can integrate crypto payments system for their company business.

The Ethereum ecosystem is bigger than BNB and BNB does not provide anything new that the eth network doesn't have. BNB just has lower transaction fees than ethereum. As soon as the ethereum network fully turned into POS from POW its gas fees will also be lower. Actually it doesn't matter because most of the project now use multi chain features.

There is a certain time when traffic in the ethereum network reduces and it's mostly in the Asian timezone I think. Gas fees are less that time so you can use that time to send your transaction. Also if you want to withdraw eth from any exchange then use FTX because it offers the lowest possible fees for eth network as I know till now.

It depends on what the reason was behind your joining that airdrop. I think 99% of people join airdrops so that they can generate some income from them. Because of the small quantity we got from an airdrop, it didn't have any significant impact on our portfolio on a long-term basis. So selling is the better option.
