Well this happen to me a long time to hold and forget to sell lmao 
and in the end the coin I hold is ended up being a scam so I got nothing. I agree when we can sell the coin so we can buy top 10 altcoins or bitcoin the safest crypto rather than long term hold a project that can be scammed anytime. I'm not sad when that happens but that becomes an experience for me so I can decide the best move for next coin/token.
It should be noted that if the coin you are holding is not a good coin then when there is value and it is good enough for you then I think at that time sell it, because there is no need to hold it any longer, in the end, it becomes a useless coin with nothing the value, I always throw away new coins even though the price is quite decent because for me coins that are not popular will tend to be a scam if held for longer. and in the end the coin I hold is ended up being a scam so I got nothing.

see some opportunity for us to do so and there are instances on which we dont care nor skip out just because we are really that aiming for long term which is something depends on someones particular goals.Yes, we dont need to hold for all of our life but it would really be basing on someones particular goals or targets which would really vary to each other.
