Two suggestions for newbies in the cryptocurrency circle (which can also be used by leeks):

1. The first lesson for entering the circle: There are too many scammers in this circle, so assume that everyone may be a scammer. Don't trust anyone's kind advice to "help you make money". This will help you avoid many pitfalls.

2. The second lesson for entering the circle: spend time screening and recording various information, learn to identify which information is effective, and keep tracking it. After all, sharpening the knife does not delay the chopping of wood. Most of the information is useless and may even mislead you.
