Selling everything is not an option, the fact is that if you sell everything right now you will lose a lot of money because of it.
I really do not recommend you to do this at all!
For me, selling everything is just the last option because I do believe that my bitcoin will give me more money that longer I hold it, I will just sell when I am in desperate need of money which I do no wish it will happen to me.
Exactly, and we should sell only part of them only if we are in need of money or else its better to hold them as price is expected to rise in future and I think that would be the right time to sell bitcoins.
