Be careful with exchanges, especially if it's a long-term investment. Try to keep it in your own wallet (of course, you can experiment a few times to avoid putting it in a scam wallet; the safest option is a cold wallet, so try to experiment and test).
So far, the only ways to make money are by doing projects, starting exchanges, doing OTC, holding Bitcoin, and being a promoter in the cryptocurrency community, providing liquidity, offering services to the crypto space, launching projects, and generating traffic. All other outcomes ultimately lead to failure.
Are there people who make money by relying on others, through hype, or by copying others in crypto? Of course, there are, but out of a thousand or ten thousand people, there's usually only one. New hype traders will keep appearing, but if you can't make a profit every time and are always losing money, then it's time to reflect and stay away from those who promote hype.
