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
I also think that intensive researches about the coins are very important. As you said, I am always trying to do my best, and I think that this bearish run have showed us that, waiting for the better prices to make buying can take a very long time.
