I used to be the person in that description of yours

When the market dipped, I bought some, hoping it will bounce back sooner, when eventually the market keep going down, I was becoming nervous, but bought some more in hope I will get  some more profit. Then, when the market finally on rise, I was waiting for the higher price, until eventually it went down again, even only slightest price reduction, I regretted it, "why didn't I sell it earlier?".

After awhile, I got exposed more information about Bitcoin and I keep educating myself about. Now, in order to maintain my mental stability, I choose to hold, that's what I learned from this forum so far.
