Watching the price of my altcoins is the most frustrating thing I might have ever done. Yes it is so frustrating and yes it maybe wrong for tons of traders but I am new to this world and I think I have to follow, get used to the patterns, know how I can manage my coins.
And you are right at FOMO & FUD part. I did the same, actually still doing. When the coins goes up I sell it directly. Thats just what I did 2 day ago. Had HPB for a long time. I was swinging everyday with 1% profit. Then %10 opportunity happened! There I was, happy, sold my precious HPBs, then it continued! Waited for the retrace to happen.
I am kinda a bag holder. Actually thats also why I am checking out the prices and hoping there was a pump while I am sleeping. Damn why my coins dont get pumped!
