Miners meet with all the phases in bitcoin cycle and it can be difficult to make profit as miners except at the bull market. We have more wealtheir investors in mining who does not sell like they used to do, to acquire as much as most whale and keep for great profit. All the aspect of bitcoin has bigger contributor that encourage a bigger hoarding.

If you are asking all this things I can tell you that mining is not for you, 100%  sure of that. This does not mean that you can't mine ever, but that you should not think about mining at this point in your life.

Learn more about the mining first, try other things out, whatever you prefer. It can be bounty hunting, freelancing for crypto project if you have some skills that can be monetized or some other things like staking some altcoins and such.

I'm not sure why you're asking this question in Meta... Move this topic somewhere else.
IMO bounties are shit nowadays. Most projects is just pure scams and almost all remaining projects isn't profitable and not worth your time and efforts. Another thing is Bitcoin paying campaigns. There you can earn quite good money without risk to be scammed. But there is not that many campaigns available.
If you don't have enough money to buy mining hardware and knowledge about it, I think you should forget about mining. Mining isn't for everyone. You can try altcoin staking, but don't expect significant earnings.
Trading, not an easy thing, but can bring good money. But of course, you need to be cold blooded, with enough knowledge and have rational thinking.
And I think you should change attitude and don't look for easiest way to earn money. Usually low effort tasks brings small returns. If you want to earn good money, hard work is needed...

The easiest is when you are only making some posters on some company and they will pay you with Bitcoin. I know some people who made a fortune with this kind of job and still doing it for the companies that hired him. If you want to know how those people made some decent amount of money from doing those jobs, you should learn first how to make some unique and good quality posters. Trading is way more complex than you think, you need to know some of the tips and tricks that would make you a crypto trader and it's not always guaranteed you to make money because if something goes wrong, you also lost your capital.

The easiest thing to do to participate in bitcoin is to buy bitcoin and hold it. It was more than enough. That includes investments made in bitcoin. Actually, there are many ways you can do it, but it has risks and deeper knowledge. Like making trades that require capital and good skills in trading.

But if you have become a miner, you have to think again. Because mining is now not as easy as it used to be and the income you get is not much. You need more mining tools and of course it will be more expensive. The use of electricity will also be very large. Don't use your smartphone or personal computer, because that would be useless and only damage it.

I think you have been misinformed. If you look at the forum, you will see  that the bounty hunters aren't doing well. They all are screaming scam and not getting paid. The way you are saying that those who do not participate in bounty programs, starts trading kinda sounds like you think bounty hunters and traders make the same profit. No, they don't. Bounty hunters make nothing compared to a trader.
Mining with your android phone? Lol, we can't even mine with a laptop, let alone a mobile phone!

My answer is also this.

The easiest for me is staking. But it's not a specific "bitcoin participation" but a cryptocurrency-related investment. Several exchanges offer to stake on their platforms but as we know, it's best if you are the one holding your coin.

The safest would be staking to a hardware wallet which is the Ledger wallet, Nano S or Nano X. The supported staking coins are still few at three but I think in the future, it will become more.

i don't think OP actually means "participation", it is a wrong work to be used here if you check the examples he used they are all ways to make money (bounty hunting, mining, trading) and there is no money to be made by running a bitcoin full node.

I'd say through investment. People may engage to mining, bounty participation, trading and the likes but the easiest way I think for a person to get into cryptos is to simply invest into it. But ofcourse reading about it, atleast the fundamentals or keyterms, is more advisable. Then if he would want to dig for more, interactions with people industry is the second step, I guess.
Good one. But cryptos including Bitcoin will more likely be heard on things related to profit such that investing into it will give "assured" profit. It is not really easy money but that's more likely how cryptos will be introduced to someone nowadays due to news. This forum is a good thing but not all people are aware of this site.
