3) If a project guarantee 100x or 200x profit return, then avoid such projects in terms of investment, as this is also a trick to trap you.
this is true, a project cannot guarantee its success and any project that makes such promises like 100x profit is surely a way to lure investors so newcomers into crypto should take note and avoid such projects. Even a well established project can fail just as the case with luna and so many other projects. Alot of people have fallen for this trick and so did i in my early days.
1) Do Your Own Research (DYOR), instead of believing in the Project Team, Ads, Marketing, Hype, etc.
This is important as well, for some projects when a new token is about to be created the project team makes lots of promises just so they get people to invest in the project so its very important to do your research before investing into a project and also do not just invest in a project when youre told to do so by anybody without doing proper research on the project.
Lots of scam project everywhere lets all be careful and carry out proper research before investing.
