1. We buy coins not only because the price is low - many had thought that buying them in bulk gives them a good profit later.
2. We have to stop thinking about hypes - maybe some but not all of the new projects
3. Stop falling to scam projects - usually, people got tricked when seeing projects offer high rewards (good to be true) and most of them are just a lie.
4. Doing Research - we have to take this seriously as nobody had ever succeeded without this.
The first 3 will be prevented if you know how to do the 4th one because if you do research first, you are equipping yourself with knowledge thus lessening the chances of losing money or fall into scams and hypes etc. Knowing which are scams and which are now will help you decide whether you need to invest into new projects or not. On the other hand, you could lose your money investing in hypes but you can still make money if you know when to enter and when to exit and if you're lucky to buy the token at its lowest price then it pumped then suddenly.
Maybe we should also consider the use or utility of the project?
You can add this as well because every time I invest into projects, I always see the use of the token and how it will help people in their lives.
