Let's recap the lesson from the recent bearish run, before u invest in any cryptocurrency.
1. make sure u do an intensive research,
2. never stop believing in urself and when things go wrong, u will learn a big lesson and be happy u did your best than following a footstep u know nothing about,
Good luck
But still, luck still plays a role here. Even though a coin or a project is really good, it doesn't mean it is going to boom. Just like in this period of time, it is a red market and the investors are not earning any money right now.
