There is no way.

If there was, everyone would be doing it.

The easiest and probably best way is to do what everybody does. Get a job, learn a skill, and work hard every day.

Don't invest in a risky asset like crypto looking for profit, you won't find it easily. Only invest in crypto with money you don't care about and can afford to lose.
Don't try to trade, if you have no experience you will only lose your hard earned money.

Anyone/anything that promises you big profits, should be a red flag in your head. There is no such thing as easy profits.
