If you want to make money from crypto, just buy and hold.
Buy and hold means invest.
By words, it sounds very easy but in practice it is so hard. Because waiting time since buying, holding and time when you can take profit sometimes is very long. A long the holding time, you will have to face with many tests in the market especially psychological and discipline tests.
If you are undisciplined, you will break your plans with greed (stop holding and change to spot trading or worse margin, future trading)
If you are unable to tolerate against fud, psychological tests in bear market and even in bull market, there are fuds too, you will exit soon than what needed to gain profit.
With many psychological phases, likely weak hands and undisciplined people will exit.
It's not easy but your advice is good: invest can help people richer with Bitcoin.
