The questions I keep on asking myself are;

1- Why did I sell all coins of my favourite? (I should I have sold a portion but I was thinking I was doing the right thing at that time, I really thought I would increase my 1661 coins to 2500 coins)
2- Why didn't I re-buy when I realised that I sold too early? (I was hoping that the dip/crash would come so I waited and risked)
3- Why did I emotionally act in this way? (When I entered the market, I told myself not to sell and was actually doing good)
4- Why didn't I profit from this crash/dip and actually ended in missing the opportunity? (Now the situation is over and I am having less than coins then before which I expected to have the opposite)
5- Will there be a new crash/dip where I can buy cheaper or will this coin keep on increasing? (I don't know the market enough to answer this and just hoping I will get the opportunity to buy more)

Now only 2 things keep myself less-guilty;
1- I didn't loose any money, just lost an opportunity
2- I have at least re-bought 603 coins and having some gains.

I cannot think of anything else other than this situation. I need suggestions to get this over as I keep on blaming myself.
