That is what actually I am thinking, it is not only trading or participating a campaign that you can earn money.
Look under the services section and see for himself what skills he can offer. There are so many ways to earn money, as you said just grind hard.
And your story is a good one, after 13 failed groups, he got the 14th one that paid off.
If he gave up early, I don\’t think he got the earning one. So it is resilience and patience that somehow are important to achieve your goals.

You can try to improve yourself, knowledge, skills, find jobs and work to have money. Use money to buy bitcoin and cryptocurrency. If you receive your job salary in bitcoin or cryptocurrency, you don’t have to buy anything.
