It really depends on your expectation for the coin, if you think it will come good in the long term then of course hold it, if you think it will never improve then get rid of it and try again.
I agree with the getting rid of if he knows it is a shit coin but trying again ?
That is like moving from frying pan and trying to get into the fire, then what is the point of selling in the first place ?
Low volume coin are usually just good for pumps which is normally organized by some group of people and some people even get burnt in the process, they have no life, no chance of growing, no chance of survival and should never be held or traded in the first place and I hope OP has learnt his lessons. Best is to sell and find a better trade to get into now.
